GSR1(12410) POS link connected to another GSR2(12410) POS Link (Primary Link)
GSR1(12410) GigE link connected to another GSR2(12410) GigE Link (Secondary Link)
Software Version: 12.0(32)SY4
Have enabled "mpls ldp sync" under my OSPF Process on both GSR's and have configured a hold-down time of 60000 msec.
I have the following doubts:
1) When I remove the mpls ip command from POS interface to make the LDP down, the traffic doesn't switches to secondary link.What may be the issue?
2) Can someone please explain when the max-metric will be advertised by OSPF. Will it be advertised after the holdtime expires or before that and what will happen if sync is not achieved.
3) Also what will happen, if I am having a single link between my routers. HOW will sync behave then ?
