[j-nsp] Active Routes on LSP - troubleshooting

[Alexander Arsenyev (GU/ETL)]

Hello,

What really happens here is a recursive prefix-to-LSP mapping. 
Firstly, BB1.REI learned 11 prefixes which have a next hop of 212.129.9.7 and they have been mapped directly into LSP BB1.REI-BB1.COU. 
Secondly, at least one of these 11 routes was used to resolve next-hop of other BGP routes and these other routes also become mapped into this LSP.
"show route next-hop <hext-hop value>" command displays only prefixes which have next-hop attribute set to the specified value, not all routes pointing to the specified next hop.
Makes sense?
HTH,
Cheers
