I'm quite new on MPLS-TE and now I'm trying to understand how fast-reroute facility-backup works.
I known that I can have two types of backup, one-to-one and many-to-one (Bypass tunnel). My question is, when router wants to configure bypass tunnel, Are network's constraints, such as bandwith, cos etc, considered? or is enough that destination is reachable?
Thanks for your help
