Hi all,
I'm trying to understand how RSVP-TE is intended to work in terms of fast-reroute. So we have one-to-one or bypass protection styles, can both be in operation on a single node at the same time? If so, how does RSVP choose which backup path to use when a failure occurs? And if not, could someone explain why?
I saw this post on here, which addresses the relationship between secondary paths and FRR, but I am still confused as to how RSVP or lower protocols would decide which path to take in the case of a failure.
In the case of a failure where we switch to a detour or bypass LSP, does RSVP change in its signalling or does it remain unaware of the failure?
Apologies for the pile of questions, RFCs are usually no problem for me to understand, but the RSVP related ones are proving hard to grasp.
