Verifying the configuration

After a tunnel is established from Router A to Router C, execute the following command on Router A:

<RouterA> display rsvp peer verbose

Peer: 10.1.1.2 Interface: GE2/1/1

Hello state: Up Hello type: Active

PSB count: 0 RSB count: 1

Src instance: 0x1f08 Dst instance: 0x22
