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:
¿ Anything I am missing to make this work?
Any hints will be greatly appreciated.
The "install-nexthop lsp" feature is supposed to be used with equal-cost LSPs.
By default, all LSPs towards the same destination irrespective of the actual path taken share the same cost equal to minimum IGP cost.
So, if You are costing out one of the LSPs then "install-nexthop lsp" feature is not expected to work. And what You are observing in Your tests is expected.
You'd need to keep the same metric/cost for all LSPs towards the same destination and then apply "install-nexthop lsp" policy.
Matching the metrics on both LSPs made the magic!
You saved my day! 🐵
Thanks a lot!!!! Rogelio
