Verification with Ping

To verify that the VPN works, all you need to do is a ping from one peer router to the other. The following output appears as the result of a ping from

Peer 2 to Peer 1. Notice that the ping works.

Peer2#ping 192.168.1.1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip in/avg/max = 116/119/120 ms

Verifying Static VRF Routes

Now you need to know about the flow of routing information through the network. Let’s begin this discussion by looking at the routing table of vpn_1 as it exists on the Atlanta POP router:

Atlanta#show ip route vrf vpn_1
