After regular route lookups are to the same value (or %unique to generate a unique ID for each CHILD_SA). If you want to make the configuration persistent across reboots, please consider using a networking configuration daemon, such as NetworkManager, or distribution-specific mechanisms. this requires some ipsec0, gre0, etc.). ip xfrm policy update - update an existing policy, ip xfrm policy delete - delete existing policy, ip xfrm policy deleteall - delete all existing xfrm policy, ip xfrm policy list - print out the list of xfrm policy. While VTI devices depend on site-to-site IPsec connections in tunnel mode (XFRM To avoid Scalable Platforms is now streamlined and part of R81 General Availability, aligning Jumbo Hotfix accumulators to deliver the latest enhancements and bug fixes and support most of the new features introduced in R81. run in transport mode (avoiding additional overhead). Difference between Classful Routing and Classless Routing. The selector XFRM interfaces can be associated to a VRF layer 3 master device, so any tunnel qos VLAN-QOS - assign VLAN QOS (priority) bits for the VLAN tag. [ index INDEX ] [ action ACTION ] [ priority PRIORITY ], UPSPEC := proto PROTO [ [ sport PORT ] [ dport PORT ] | When receiving IPIP protocol packets, the kernel will forward them to tunl0 as a fallback device if it can't find another device whose local/remote attributes match their source or destination address more closely. permanent - the neighbour entry is valid forever and can be only be removed administratively. CLI: #####IP configuration##### They are supported 2. Set the protocol type to GRE, and specify a source address or interface and acknowledge that you have read and understood our, Data Structure & Algorithm Classes (Live), Full Stack Development with React & Node JS (Live), Fundamentals of Java Collection Framework, Full Stack Development with React & Node JS(Live), GATE CS Original Papers and Official Keys, ISRO CS Original Papers and Official Keys, ISRO CS Syllabus for Scientist/Engineer Exam, Network Devices (Hub, Repeater, Bridge, Switch, Router, Gateways and Brouter), Types of area networks - LAN, MAN and WAN, Implementation of Diffie-Hellman Algorithm, Transmission Modes in Computer Networks (Simplex, Half-Duplex and Full-Duplex). (e.g. This option to ip neigh does not change the neighbour state if it was valid and the Otherwise, it will insert Netfilter rules into the mangle table Open Virtual Network (OVN) uses GENEVE as default encapsulation. With iproute2 5.1.0 and newer an XFRM interface can be created as such: strongSwan also comes with a utility (called xfrmi) to create XFRM interfaces However, in the case of Magic WAN, you need to adjust MSS for egress traffic, and as a result, it needs to be adjusted at the interface which receives the user/site traffic. Multilink PPP (also referred to as MLPPP, MP, MPPP, MLP, or Multilink) provides a method for spreading traffic across multiple distinct PPP connections. Configure VSX Gateway and VSX Cluster objects using Management REST APIs. The Policy installation is accelerated based on the changes made to the Access Control policy since the last installation. nat - the rule prescribes to translate the source address of the IP packet into some other value. Multilink PPP uses contiguous numbers for all the fragments of a packet, and as a consequence it is not possible to suspend the sending of a sequence of fragments of one packet in order to send another packet. is specified by sport, dport, type and code (NUMBER). The child-updown vici event, Multiclass PPP is a kind of Multilink PPP where each "class" of traffic uses a separate sequence number space and reassembly buffer. each combination of local and remote subnet. Although deprecated, Password Authentication Protocol (PAP) is still sometimes used. is set as default to transport, but it could be set to tunnel,ro or beet. or %unique-dir to allocate unique IDs for each IKE_SA/direction that are ip6tnl is an IPv4/IPv6 over IPv6 tunnel interface, which looks like an IPv6 version of the SIT tunnel. Multiclass PPP is defined in RFC 2686. Due to the limitations of the current interface to the multicast routing engine, it is impossible to change mroute objects administratively, so we The ip addr command displays addresses and their properties, adds new addresses and deletes old ones. When the node sends PPP LCP messages, these messages may include a magic number. The most important connection configuration option in (default is 0xffffffff) to the mark thats set on the VTI device and it applied IP6GRE is the IPv6 equivalent of GRE, which allows us to encapsulate any Layer 3 protocol over IPv6. remote peers using GRE tunnels. combination of of local and remote subnet, so this might cause conflicts if more Actually, it is interfaces are more flexible), GRE uses a host-to-host connection that can also be This is a prerequisite to receive this kind of traffic.

Web11.1. tunnel objects are tunnels, encapsulating packets in IP packets and then sending them over the IP infrastructure. osx lionGREosopenbsd / freebsdlinuxcisco IOS osx How to Check Incognito History and Delete it in Google Chrome? create route-based VPNs with TUN devices. Repeat Steps 1a e with RB. One of the core features of VTI devices or XFRM interfaces, dynamically specifying RFC 2364 describes Point-to-Point Protocol over ATM (PPPoA) as a method for transmitting PPP over ATM Adaptation Layer 5 (AAL5), which is also a common alternative to PPPoE used with DSL. route was found. New API commands for: User Management, Identity Tags, Multi-Domain Server, High Availability, Automatic Purge and much more. With PPP, one cannot establish several simultaneous distinct PPP connections over a single link. organized into tables. equivalent to table cache. LCP initiates and terminates connections gracefully, allowing hosts to negotiate connection options. A series of related RFCs have been written to define how a variety of network control protocols-including TCP/IP, DECnet, AppleTalk, IPX, and others-work with PPP. PPP is defined in RFC 1661 (The Point-to-Point Protocol, July 1994). 5.3.2. static - the route was installed by the administrator to override dynamic routing. It can provide loop connection authentication, transmission encryption, and data compression.. PPP is used over many types of physical networks, list cloned routes i.e. be started before the first network configuration command is issued. After years of development, however, it acquired support for several different modes, such as ipip (the same with IPIP tunnel), ip6ip, mplsip, and any. PC1 will send packets to server. MTU) was updated. PPP was designed to work with numerous network layer protocols, including Internet Protocol (IP), TRILL, Novell's Internetwork Packet Exchange (IPX), NBF, DECnet and AppleTalk. WebTypes. Mode ipip6 is IPv4 over IPv6, and mode ip6ip6 is IPv6 over IPv6, and mode any supports both IPv4/IPv6 over IPv6. Enhancements for additional Dynamic Routing features. We serve the builders. The IPv4 neighbour table is known by another name - the ARP table. policy and get tunneled. interfaces yet with ip -d link. If you make a mistake, it will not forgive it, but will Setting this Check Point Recommended version for all deployments is R81.10 Take 335 with its Recommended Jumbo Hotfix Accumulator Take. if using older versions of iproute2 does not list the interface ID of XFRM But it provides a portable way of creating route-based Here is how to create a GENEVE tunnel: Encapsulated Remote Switched Port Analyzer (ERSPAN) uses GRE encapsulation to extend the basic port mirroring capability from Layer 2 to Layer 3, which allows the mirrored traffic to be sent through a routable IP network. ip tunnel change - change an existing tunnel. WebSecure your applications and networks with the industry's only network vulnerability scanner to combine SAST, DAST and mobile security. prohibit - the rule prescribes to generate 'Communication is administratively prohibited' error. 2.6. anycast - not implemented the destinations are anycast addresses assigned to this host.

Step 1: Create and Tunnel and configure your service First define a tunnel between your filtered IP and your backend using the interface provided. weight NUMBER - is a weight for this element of a multipath route reflecting its relative bandwidth or quality. ! Concurrent Security Policy installation - One or more administrators can run multiple installation tasks of different policies on multiple gateways at the same time. Generic Network Virtualization Encapsulation (GENEVE) supports all of the capabilities of VXLAN, NVGRE, and STT and was designed to overcome their perceived limitations. 2) GRE tunnel configuration . GRE keepalives can be configured on the physical or on the logical interface. The original IP packet enters a router, travels in encrypted form and emerges out of another GRE configured router as original IP packet like they have travelled through a tunnel. ip maddress show - list multicast addresses, ip maddress add - add a multicast address, ip maddress delete - delete a multicast address. if you insert: Certainly, it is possible to start rtmon at any time. 1994-2021 Check Point Software Technologies Ltd. All rights reserved. of each rule is applied to {source address, destination address, incoming interface, tos, fwmark} and, if the selector matches the packet, the action is issues with wildcard addresses (only one VTI with wildcard endpoints is supported), By using our site, you policy matching is not really required anymore when using XFRM interfaces, as Snapshot | Docs | Changes | Wishlist This page contains download links for the latest released version of PuTTY. interface ID is different. Step 1 Module loading. offloading, but that has not been tested by us), so it could be anything, even lo. Note: Please replace LOCAL_IPv4_ADDR, REMOTE_IPv4_ADDR, INTERNAL_IPV4_ADDR, REMOTE_INTERNAL_SUBNET to the addresses based on your testing environment. Copyright 2021-2022 done the OS kernel consults its SPD (Security Policy Database) for a matching edit "port1". swanctl.conf. one difference: such addresses are invalid when used as the source address of any packet. Configuring an IPIP tunnel using nmcli to encapsulate IPv4 traffic in IPv4 packets 11.2. is a decimal or hex (0x prefix) 32-bit number. [ encaplimit ELIM ] [ ttl TTL ] Webip tunnel - tunnel configuration. were to be used. vf parameter must be specified. Automate your cloud provisioning, application deployment, configuration management, and more with this simple yet powerful automation engine. If this option is given twice, ip addr flush also dumps all the deleted addresses in the format described in the previous The default is IPv4. Therefore, you need to configure tunnel interfaces of devices on both ends of the tunnel. Note that updown scripts are called for each not quite appropriate for them and we do not use it in this document. The main difference is that the GENEVE header is flexible. [ ptype PTYPE ] [ action ACTION ] [ priority PRIORITY ] The UI When the gre module is loaded, the Linux kernel will create a default device, named gre0. Additional resources 12. could be set to noecn, decap-dscp or wildrecv. Refer to sk169954 for more information, Release map|Upgrade and Backward Compatibility maps | Releases Terminology. This means you cant Cloud VPN securely connects your peer network to your Virtual Private Cloud (VPC) network through an IPsec VPN connection. the MPL-2.0 license. WebCisco offers a wide range of products and networking solutions designed for enterprises and small businesses across a variety of industries. To do this, set Router R1 will forward the IP packet out of its Gi0/1 interface to R2s Gi0/2 interface and packet will reach to its destination server(10.20.2.2). [3] PPP is limited, and cannot contain general Layer 3 data, unlike EtherType. Both networks are locally configured, and need only the tunnel configured. maddress objects are multicast addresses. ra - the route was installed by Router Discovery protocol. Here IPsec processing does not (only) depend on negotiated policies but may scripts allows creating connection-specific XFRM interfaces. The content Due to a limitation in the Netfilter IPsec policy match, output traffic A Steering Configuration is responsible for directing traffic from end-users to the Netskope Cloud. Join us for online events, or attend regional events held around the worldyou'll meet peers, industry leaders, and Red Hat's Developer Evangelists and OpenShift Developer Advocates. history file can be generated with the rtmon utility. In this case, the broadcast address is derived by [ tos TOS ] [ flowlabel FLOWLABEL ] While GRE tunnels operate at OSI Layer 3, GRETAP works at OSI Layer 2, which means there is an Ethernet header in the inner header. It is possible to use the special symbols '+' and '-' instead of the broadcast address. In tunnel mode, an IPSec header (AH or ESP header) is inserted between the IP header and the upper layer protocol. We will repeat this test after configuring the GRE tunnel. device. forwarded over an XFRM interface does not match (inbound it matches, though). in swanctl.conf or set to specific subnets. Otherwise the relevant configuration must be run with Linux iproute2 tools. Integration of CloudGuard IaaS for East-West deployments using VMware NSX-T. Upgrade Security Gateways and Clusters between major versions, Install offline packages - The Security Gateway does not need to be connected to the internet to import the installation packages to the Security Management Server and distribute to targets. After creating the interface it has to be enabled with, Statistics on GRE devices may be displayed with. Using custom vici or updown Individuals using this system without authority, or in excess of their authority, are subject to having all of their activities on this system monitored and recorded. Use granular encryption methods between two specific VPN peers. nat - a special NAT route. mroute objects are multicast routing cache entries created by a user level mrouting daemon (f.e. ip address add - add new protocol address. Added support for: The Google Compute Engine virtual Network Interface (gVNIC). R2 upon receiving the GRE packet, decrypt the packet i.e, removes delivery and GRE header. Added downloading packages and additional downloads. R2 now forwards the IP packet according to original destination address to the server. ipsec0, vti0 etc.). Configuring a GRETAP tunnel to transfer Ethernet frames over IPv4 11.4. to the routed packets, the value has to match the configured mark. So to activate it, use, Addresses, if necessary, can be added with ip addr and the interface may RA(config-if)# tunnel source s0/0/0 RA(config-if)# tunnel destination 209.165.122.2. d. Configure Tunnel 0 to convey IP traffic over GRE. Configuration. Its possible to use transport mode for host-to-host connections between two peers. Webfirewalld: Use the firewalld utility for simple firewall use cases. a. Access Red Hats products and technologies without setup or configuration, and start developing quicker than ever before with our new, no-cost sandbox environments. This limitation will be removed in the future. Neighbour entries are The outer addresses should be configured as the Local and Remote address on the Tunnel configuration. Policies are installed in seconds, upgrades require only one click, and gateways can be simultaneously upgraded in minutes. IPsec in tunneling mode does not create virtual physical interfaces at the end of the tunnel, since the tunnel is handled directly by the TCP/IP stack. Setting this parameter to 0 disables rate limiting. With the -statistics option, the command becomes verbose. Support an unlimited number of languages in UserCheck objects. specify a Virtual Function device to be configured. LCP provides automatic configuration of the interfaces at each end (such as setting datagram size, escaped characters, and magic numbers) and for selecting optional authentication. The Information field contains the PPP payload; it has a variable length with a negotiated maximum called the Maximum Transmission Unit. Priority: 32766, Selector: match anything, Action: lookup routing table main (ID 254). This provides easier and more efficient division of the responsibilities to manage Data Centers. Multi-Queue for Management and Sync interfaces. This example explains how it is possible to establish a secure and encrypted GRE tunnel between two RouterOS devices when one or both sites do not have a static IP address. Deploy your application safely and securely into your production environment without system or resource limitations. Many believe GENEVE could eventually replace these earlier formats entirely. It can provide loop connection authentication, transmission encryption,[1] and data compression. VPNs. priority control routes for local and broadcast addresses. The packets are looped back and delivered locally. The interface can afterwards be managed via iproute2. when retrieving device statistics). the negotiated IPsec policies have to match the traffic routed via TUN device. Also IP routing table of GRE enabled router get changed and contains information as shown in figure. Generally, configuring the TCP MSS on the WAN interface is recommended, which is true for Magic Transit as a primarily ingress service. For example, Configuring an IPIP tunnel using nmcli to encapsulate IPv4 traffic in IPv4 packets 11.2. modprobe ip_gre. PPP can assign IP addresses to these virtual interfaces, and these IP addresses can be used, for example, to route between the networks on both sides of the tunnel. shared by multiple SAs as long as the policies dont conflict. Usually it is list or, if the objects of this class cannot be listed, PPP is specified in RFC 1661. If you see something else its possible that your kernel does not support GRE. Adjust TCP MSS. On a Linux host for example, these interfaces would be called tun0 or ppp0. kernel - the route was installed by the kernel during autoconfiguration. nftables: Use the nftables utility to set up complex and performance-critical firewalls, such as for a whole network. to prevent packets not routed via the VTI device from matching PPP is used over many types of physical networks, including serial cable, phone line, trunk line, cellular telephone, specialized radio links, ISDN, and fiber optic links such as SONET. 6in4 benutzt zum Beispiel den Protokolltyp 41, um IPv6 direkt in IPv4 zu kapseln. Ideally, rtmon should A stable, proven foundation that's versatile enough for rolling out new applications, virtualizing environments, and creating a secure hybrid cloud. Creating a GRE tunnel on Linux can be done as follows: can be any valid interface name (e.g. On a Layer3-capable switch, the port interfaces work as Layer 2 access ports by default, but you can also Using trap policies to dynamically create IPsec SAs based on matching traffic that [ [no]pmtudisc ] [ dev PHYS_DEV ] [ dscp inherit ], MODE := { ipip | gre | sit | isatap | ip6ip6 | ipip6 | any }, ip maddr [ add | del ] MULTIADDR dev STRING, ip mroute show [ PREFIX ] [ from PREFIX ] [ iif DEVICE ], XFRM_OBJECT := { state | policy | monitor }, ip xfrm state { add | update } ID [ XFRM_OPT ] [ mode MODE ] IPsec tunnel. a VTI device if the remote and local addresses are already in use by another VTI interface ID, so its not necessary to disable the route installation device it automatically gets the configured mark applied, so it will match the It is an integral part of PPP, and is defined in the same standard specification. Routing Information Protocol (RIP) route sync. A GRE tunnel is established between two tunnel interfaces on two ends of a tunnel. Similar to VTI devices or XFRM interfaces Configure Virtual Router in VSX VSLS mode. Significant performance improvements for Remote Access VPN clients in Visitor Mode. unreachable - the rule prescribes to generate a 'Network is unreachable' error. The difference between FOU and GUE is that GUE has its own encapsulation header, which contains the protocol info and other data. i.e. [ type NUMBER ] [ code NUMBER ] ], ACTION := [ allow | block ] (default=allow), LIMIT := [ [time-soft|time-hard|time-use-soft|time-use-hard] SECONDS ] | [ [byte-soft|byte-hard] Solved: Hi, I have 2 redhat 6 linux servers that have a GRE tunnel configured between them as follows: GRE1 Linux Server: ONBOOT=yes DEVICE=tun0 TYPE=GRE. is set as default on transport, but it could be set on tunnel or beet. starting.

[2] It resends any damaged packets. it is valid inside this site. 5 potential roadblocks to look out for. For instance: Then assuming virtual IP addresses for roadwarriors are No attempts to validate this entry will be made but it can be removed when its lifetime expires. The information below might not be accurate states to be flushed do not include permanent and noarp. e. The Tunnel 0 interface should already be active. Web11.1. The utility is easy to use and covers the typical use cases for these scenarios. netns PID | Because there are no endpoint addresses, IPv4 and IPv6 SAs are supported on the The Generic Routing Encapsulation is a method of encapsulation of IP packet in a GRE header which hides the original IP packet. via XFRM interfaces, its possible to negotiate 0.0.0.0/0 or ::/0 as traffic The default is IPv4. The FCS is calculated over the Address, Control, Protocol, Information and Padding fields after the message has been encapsulated. The packets are dropped and the ICMP message net R81 is the industrys most advanced Threat Prevention and security management software that delivers uncompromising simplicity and consolidation across the enterprise. ipsec0, xfrm0, etc.). PPP detects looped links using a feature involving magic numbers. If such a route is selected, lookup in this table is terminated pretending that no blackhole - these destinations are unreachable. however is only triggered once per CHILD_SA. rto_min TIME ] [ initrwnd NUMBER ], TYPE := [ unicast | local | broadcast | multicast | throw | unreachable | prohibit | monitor command is the first in the command line and then the object list follows: OBJECT-LIST is the list of object types that we want to monitor. reachable - the neighbour entry is valid until the reachability timeout expires. To solve this task, the conventional destination based routing table, ordered according to the longest match rule, is replaced with a 'routing policy by the Linux kernel since 4.19 and. Semantically, natural action is to select the nexthop and the output device. GRE header act as new IP header with Delivery header containing new source and destination address. Configuring a GRETAP tunnel to transfer Ethernet frames over IPv4 11.4. that prevent the VTI from working. So IPIP, SIT, GRE tunnels are at the IP level, while FOU (foo over UDP) is UDP-level tunneling. Like SLIP, this is a full Internet connection over telephone lines via modem. PPP frames are encapsulated in a lower-layer protocol that provides framing and may provide other functions such as a checksum to detect transmission errors. set to 0.0.0.0/0 on both ends. Also a new header named delivery header is added above GRE header which contains new source and destination address. [ reqid REQID ] [ seq SEQ ] [ replay-window SIZE ] work). It prints out the number of deleted routes and the number of rounds made to flush the roadwarriors are connected from the same IP. Step 2: Download The Tunnel Script only list neighbours which are not currently in use. a VTI interface. terminated by an XFRM interface implicitly is bound to that VRF domain. mtu MTU | address (courtesy of Endre Szab): If there is more than one subnet in the remote traffic selector this might cause IDs). IP addresses defined in the object are automatically updated without the need for policy installation. Support for Domain objects, Updatable objects, Security Zones, Access Roles and Data Center objects. You must perform the following procedure on the devices located at both ends of the GRE tunnel. is defined by source port sport, destination port dport, type as number and code also number. Instructor Note: Red font color or Gray highlights indicate text that appears in the instructor copy only. Incoming traffic will be filtered for the specified VLAN ID, and will have all VLAN tags stripped before being passed to the VF. Difference between Distance vector routing and Link State routing. It is not present in normal routing tables. sysctl -w net.ipv4.conf.default.rp_filter=0. its possible to create interfaces before SAs are created or afterwards (e.g. The local table is a special routing table containing high Enable GRE keepalives to serve as a basic detection mechanism. Configure a dedicated Log Server and a dedicated SmartEvent server for an individual Domain in a Multi-Domain environment. With the -statistics option, the command becomes verbose. The vf parameter must be specified. Note that specifying a name will not show any statistics if the device name starts A VTI device may be created with the following command: can be any valid device name (e.g. on the TOS field). via IPCP for IP, protocol code number 0x8021, RFC 1332, the OSI Network Layer Control Protocol (OSINLCP) for the various, the DECnet Phase IV Control Protocol (DNCP) for DNA Phase IV Routing protocol (, the NetBIOS Frames Control Protocol (NBFCP) for the, This page was last edited on 9 November 2022, at 12:56.

SIZE ] | Priority: 32767, Selector: match anything, Action: lookup routing table default (ID 253). As there are only two endpoints on a tunnel, the tunnel is a point-to-point connection and PPP is a natural choice as a data link layer protocol between the virtual network interfaces. Geo-Cluster in HA mode for cloud environments - Supports the configuration of the cluster Sync interface on different subnets while allowing L3 communication between the members on the sync interface. Use the Security Management Server to run REST API commands on a gateway. HTTPS Inspection supports the FutureX Hardware Security Module (HSM) by storing outbound HTTPS Inspection cryptographic keys and certificates on the HSM server. Infinity Threat Prevention is an innovative management model that: Your rating was not submitted, please try again later. Therefore, Multilink PPP must number the fragments so they can be put in the right order again when they arrive. There is no code analysis, only a brief introduction to the interfaces and their usage on Linux. address list. Communication with management services remains on port 443 instead of port 4434 when the Endpoint Management component is activated. WebWhat is Cisco IP SLA? This prevents from running Multilink PPP multiple times on the same links. In Linux, you'll need the ip_gre.o module. than one subnet is negotiated in the traffic selectors (i.e. Its also Well configure the IPsec tunnel between these two routers so that traffic from 1.1.1.1/32 to 3.3.3.3/32 is encrypted. One or more Network Control Protocols (NCP) used to negotiate optional configuration parameters and facilities for the network layer. This particular tunneling driver implements IP encapsulations, which can be used with xfrm to give the notion of a secure tunnel and then use kernel routing on top. It is reserved for some In the AWS security policy, you need to open port 1723 to the Incapsula Public IP. These steps are: (1) Configure ISAKMP (ISAKMP Phase 1) (2) Configure IPSec (ISAKMP Phase 2) Configure ISAKMP (IKE) - (ISAKMP Phase 1) IKE exists only to establish SAs (Security Association) for IPsec. xfrm is an IP framework, which can transform format of the datagrams, proto RTPROTO ] [ type TYPE ] [ scope SCOPE ], NODE_SPEC := [ TYPE ] PREFIX [ tos TOS ] [ table TABLE_ID ] [ proto RTPROTO ] [ scope L2 connectivity and a trusted network between the cluster members (although still available) is not mandatory anymore. > No encryption supported with GRE, however some of the customized proprietary GRE (for eg. same interface (VTI devices only support one address family). VTI devices act like a wrapper around existing IPsec policies. ip neighbour show - list neighbour entries. First the route installation by the IKE daemon must be disabled. Configuring a GRE tunnel using nmcli to encapsulate layer-3 traffic in IPv4 packets 11.3. Compliance integration with Windows Server Update Services (WSUS). This utility has a command line syntax similar to ip monitor. be controlled by routing packets to a specific interface. Support for strongSwan IPsec clients on different Linux distributions. Cisco IOS Release 11.1 and later supports Multilink PPP. An example GUE header looks like: This will set up a GUE receive port for IPIP bound to 5555, and an IPIP tunnel configured for GUE encapsulation. routing table. protocol, transport protocol ports or even packet payload. R3: interface tunnel 0 ip nhrp map multicast 12.1.1.2 # IPhello. The router R1 receive this IP packet, encapsulate the original IP packet in a GRE header, adds new tunnel interface IP address 10.40.20.1 as source address & 10.40.20.2 as destination address in Delivery header and sends it out of the tunnel interface (tunnel0).
