[j-nsp] Active Routes on LSP - troubleshooting

[Richmond, Jeff (ELI)]

Also, for your show route command, don't use terse if you want to see any
LSP info:

show route next-hop 212.129.9.7

If your routes are indeed using an LSP, it will be displayed. Example:

user at Scotch> show route next-hop 207.173.7.19    

inet.0: 147278 destinations, 147303 routes (147277 active, 0 holddown, 1
hidden)
+ = Active Route, - = Last Active, * = Both

0.0.0.0/0           [BGP/170] 1w2d 19:40:27, localpref 100, from
207.173.7.19
                      AS path: I
                    > via so-0/2/0.0, label-switched-path
SCOTCH->GUINNESS--LOW_PRIORITY
                      via so-0/2/0.0, label-switched-path
SCOTCH->GUINNESS--HIGH_PRIORITY
10.9.9.0/24         [BGP/170] 1d 21:45:32, localpref 100, from 207.173.7.19
                      AS path: I
                    > via so-0/2/0.0, label-switched-path
SCOTCH->GUINNESS--LOW_PRIORITY
                      via so-0/2/0.0, label-switched-path
SCOTCH->GUINNESS--HIGH_PRIORITY

If I would have added terse, it would have just shown the sonet interfaces,
without the LSP info...

Hi Jerome,

check:
show route table inet.3 (contains all mpls routes)
or
show route table mpls.0
