Verify that each Services Router's inet.3 routing table has an LSP for the loopback address on each of the other routers.
From the CLI, enter the show route table inet.3 command.
user@r5> show route table inet.3
inet.3: 2 destinations, 2 routes (2 active, 0 holddown, 0 hidden)
+ = Active Route, - = Last Active, * = Both
10.0.9.6/32 *[LDP/9/0] 00:05:29, metric 1
> to 10.0.8.5 via ge-0/0/0.0
10.0.9.7/32 *[LDP/9/0] 00:05:37, metric 1
> to 10.0.8.10 via ge-0/0/1.0
The output shows the LDP routes that exist in the inet.3 routing table. Verify that an LDP-signaled LSP is associated with the loopback addresses of the other routers in the MPLS network.
