[j-nsp] Active Routes on LSP - troubleshooting

[Jerome Fleury]

Hi, 

I have a MPLS behavior which I'd like some Juniper guru to explain to me:

jfl at BB1.REI> show mpls lsp name BB1.REI-BB1.COU
Ingress LSP: 35 sessions
To              From            State Rt ActivePath       P     LSPname
212.129.9.7     212.129.9.38    Up  6416                  *     BB1.REI-BB1.COU
                                    ^^^^
It tells me that this LSP has 6416 Active Routes, which looks a bit too much to me, according
to my limited MPLS setup. So I'm looking for those routes:

jfl at BB1.REI> show route next-hop 212.129.9.7 terse 
(I suppose this is the right command)

inet.0: 155111 destinations, 309778 routes (155110 active, 0 holddown, 1 hidden)
+ = Active Route, - = Last Active, * = Both

A Destination        P Prf   Metric 1   Metric 2  Next hop        AS path
* 62.4.0.0/19        B 170        100            >so-0/0/0.0      I
* 62.210.0.0/16      B 170        100            >so-0/0/0.0      I
* 83.152.0.0/13      B 170        100            >so-0/0/0.0      I
* 194.149.160.0/19   B 170        100            >so-0/0/0.0      I
* 195.154.0.0/16     B 170        100            >so-0/0/0.0      I
* 212.47.224.0/19    B 170        100            >so-0/0/0.0      I
* 212.62.128.0/18    B 170        100            >so-0/0/0.0      I
* 212.83.128.0/18    B 170        100            >so-0/0/0.0      I
* 212.129.0.0/18     B 170        100            >so-0/0/0.0      I
* 213.36.0.0/16      B 170        100            >so-0/0/0.0      I
* 213.195.0.0/18     B 170        100            >so-0/0/0.0      I

OK, I have 11 routes with this next-hop, so they are supposed to use this LSP.

1/ why doesn't this command work:
jfl at BB1.REI> show route label-switched-path BB1.REI-BB1.COU

it returns 0 route, when it should return at least 11 routes, shouldn't it ?

2/ what are those 6416 routes that the first output indicates ?

3/ What is the 'official' or 'recommended' way to look for those Active Routes ?

Any help on this appreciated.

Thanks.

Jerome.
