Hello team:
I have two RSVP LSPs built on my PE to reach a remote PE´s loopback address (iBGP environment).
I want the worst (in metric terms) of these LSPs to forward traffic to specific VRF routes announced by the remote PE (the ones that the remote PE announce with a specific BGP community)
For this purpose I was told to use the "routing-options forwarding-table export <policy>" command, calling the router to use a specific LSP if the community matches what I want.
I have not had success:
- if I call the install-nexthop command without the "strict" option, then the router just ignores me and keeps using the LSP with best metric to the destination PE
- if I call the install-nexthop with the "strict" option, the router changes the VRF destination routes to "hidden" (Next hop type: Unusable)
- if I temporarily deactivate the "best LSP", now the router does install the destination VRF routes using the remaining LSP, regardless of whether I use the "strict" option or not. This is what I would like to happen, but at the expense of having to erase one LSP.
¿ Anything I am missing to make this work?
Any hints will be greatly appreciated.
Best regards
