Running 2 Routerboard 1100's have vpls tunnel connecting 2 locations.
after a circuit failure upstream,between the 2 locations , the link didn't come back up, till it was manually reset.
Running ROS 5.15 on router A and 5.11 On router B
did you find a solution for your problem? I did experience the same problem last night when an ethernet port went down for 12 seconds.
I'm using RSVP TE instead of LDP. The tunnel was "on hold" after that until reset.
