Tunneling is a concept where we put packets into packets so that they can be transported over certain networks. We Provide Technical Tutorials and Configuration Examples about TCP/IP Networks with focus on Cisco Products and Technologies. After it is done, we will proceed with the configuration. Go to the global configuration mode and enter the following commands: interface FastEthernet0/0 ip address 192.168.1.1 255.255.255. We will follow below diagram for our LAB. The objective is to configure a GRE tunnel to allow LAN to LAN communication for computers on the networks behind both routers. Diagram When a destination route is in the Active state it means that a topology change has just occurred for that particular destination network. Service providers often meet the requirement for specific VLAN IDs and the number of VLANs to be supported from the customer end. It is the first step in configuring EIGRP on a router as done here on R1: R1>enable R1#configure terminal Enter configuration commands, one per line. You can verify it by pinging, Configure a static route on your router device (this will direct traffic toward it). Configuring IPSec Phase 1 (ISAKMP Policy). We will not go into the details of IP address configuration and assume that all IP addresses have been pre-configured on all interfaces including the Loopback interfaces as shown in the figure. For example: 3) After both inside (source IP) and outside (destination IP) this packet enters VPN tunnel. If you like the config as is, you can write mem, otherwise reload the router to clear and start again. If anyone does spot any errors/issues please let me know so I can amend this guide. Step 2: Configuring a VPN policy on Site B Cisco ASA Firewall Step 3: How to test this scenario. Moreover, each destination can be shown as either Passive or Active. We previously wrote about how to set up a generic routing encapsulation (GRE) tunnel for Incapsula IP Protection on an Ubuntu AWS Client. First lets configure ISP inside links. The firewall config above is just a basic setup for testing and enthusiast use, it will need to be more thorough if you are to use it in a production environment. We use a combination of SLAAC & DHCPv6, as DNS servers can't be automatically configured with just SLAAC at the moment. Configuring the IPSec Tunnel on Cisco Router 1 Configuring the Phase 1 on the Cisco Router R1 I assumed that you have reachability to the Remote Network. EIGRP is Cisco proprietary which means it is available only on Cisco routers and switches. The first step is to configure your firewall device with the appropriate tunnel interfaces. Setting up a GRE Tunnel on a Cisco Router. If you want the route to be symmetric, as a final step, configure policy-based routing to ensure the symmetric flow. Configure basic CBAC inspect rules, inspect tcp can't be used with tunnelled IPv6 connections at the moment, it causes horrendously slow throughput. Enter a Tunnel Name and a Pre-Shared Key. D 172.16.13.0 [90/2195456] via 192.168.12.1, 00:00:35, Serial0/0 Enter configuration commands, one per line. http://en.wikipedia.org/wiki/Comparison_of_IPv6_support_in_operating_systems Opens a new window i am going to read more from this website! On your router, configure network address translation from the Incapsula Protected IP to your current server IP. The router would send EIGRP messages and try to establish adjacencies with other EIGRP speaking routers off these interfaces. ! interface Tunnel5 These steps are: (1) Configure ISAKMP (ISAKMP Phase 1) (2) Configure IPSec (ISAKMP Phase 2, ACLs, Crypto MAP) Our example setup is between two branches of a small company, these are Site 1 and Site 2. tunnel source We need to specify a source and destination IP address to build the tunnel and well use the 192.168.13.0 /24 subnet on the tunnel interface. After this is done, we can proceed to configure your firewall device with the appropriate tunnel interfaces. Below are the configuration of Customer A (CusA). A destination is in the Passive state when the other routers know about a way to reach this destination. R3(config)#router eigrp 100 That completes your configuration. R2(config)#router eigrp 100 GRE Tunnel Static Route . Seem there is no special configuration needed on the customer switches, you can just connect the CusA-S1 and CusA-S2 directly with physical cable and it will work.
