MPLS TE path preemption
hello,everybody. i'd like to ask is there any preemption mechanism among TE path
say if you have a tunnel with 2 paths : dynamic and explicit.. Explicit is used first. when link is down in the network,dynamic is used.
but what if that link comes up again.. how the originally selected explicit path can be preempted back automatically. Is that possible?
i mean not creating another tunnels,or using fast-reroute option..
