Hello.
I have configured LDP graceful restart (GR) )on two routers (the same configuration):
mpls ldp graceful-restart timers neighbor-liveness 100
mpls ldp graceful-restart timers max-recovery 110
mpls ldp graceful-restart
Next I set TCP filter on both sites to filter 646 TCP port. But GR seems to not work - my session comes down and GR config with:
R11#sh mpls ldp neighbor 1.1.1.1 graceful-restart
Peer LDP Ident: 1.1.1.1:0; Local LDP Ident 11.11.11.11:0
TCP connection: 1.1.1.1.646 - 11.11.11.11.35682
State: Oper; Msgs sent/rcvd: 4/16; Downstream
Up time: 00:00:03
Graceful Restart enabled; Peer reconnect time (msecs): 0
R11#
*Mar 1 17:17:53.815: %LDP-5-GR: GR session 1.1.1.1:0 (inst. 4): interrupted--recovery failed
*Mar 1 17:17:53.819: %LDP-5-NBRCHG: LDP Neighbor 1.1.1.1:0 (4) is DOWN (Session KeepAlive Timer expired)
R11#
R11#sh mpls ldp neighbor 1.1.1.1 graceful-restart
R11#sh mpls ldp neighbor 1.1.1.1 graceful-restart
ANd all bindings are gone as well. Please help. Why it does not work?
