[j-nsp] Active Routes on LSP - troubleshooting

[Alexander Arsenyev (GU/ETL)]

Hello,

My pleasure.
The routes mapped into LSP BB1.REI-BB1.COU should be in inet.3 table and to display them all
"show route table inet.3 terse | match BB1.REI-BB1.COU" should work for You, I reckon.
HTH,
Cheers,
Alex

This is it indeed! I've found a lot of routes that resolve on those 11 BGP aggregates inside my
network. This is an unwanted behavior that I need to fix.

Thanks very much for pointing this out Alexander.

Do you know any CLI way to show all those prefix-to-LSP mappings ?
