I use IOS code 7200 Software (C7200-SPSERVICESK9-M), Version 12.2(33)SRC3
at default MPLS FRR works fine
when I shutdown pos interface on primary path, FRR works fine, but after I bring back pos interface, I noticed tu1 still use backup path
until I shut and no shut tu1
anyone could shred a light?
this is normal the best path is not used as soon as it is up again, but when the next optimization time is triggered.
you should use show mpls traffic-eng tunnels brief
to see this.
Hope to help
