Basic VRF Lab

Step 1 : Assign Ip address at Fa 0/0 of R1 and R2.
Step 2 : Configure Vrf R1 on router R1 and add Loopback 0 and 11 to this vrf
Step 3 : Configure Vrf R2 on router R2 and add Loopback 0 and 11 to this vrf
Step 4 : Configure the tunnel1 interface on both routers. Make sure the source and destination IP addresses of the Fastethernet link are used for this.
Step 5 : Make sure the tunnel1 interface is added to VRF R1 and R2 .
Step 6 : Configure the 192.168.1.0 /24 subnet on the tunnel1 interface.
Step 7 : Configure EIGRP AS 100 as the routing protocol for these VRFs. Make sure both routers can ping each others loopback interfaces.

Note :::::  interfaces must be assigned to a VRF before being addressed; assigning an interface to a VRF wipes any IP addresses already configured on that interface.

:::::Task To do:::::

sh ip route
sh ip route vrf
R1#ping 2.2.2.2
R1#ping vrf R1 2.2.2.2
R1#ping vrf R1 2.2.2.2 loopback 0
