Hi
I have a couple of GSR's and 7600'2 running ldp in an an MPLS test environment.
All of a sudden 1 GSR has lost all its LDP neighours. I have cleared the mpls
ldp neighours, and finally ended up rebooting the router with no success
Here is an brief output of some ldp commands:
---------here the LDP suddenly dropped--------
Nov 6 14:44:45 GMT: %SYS-5-CONFIG_I: Configured from console by vty0
(5.14.64.1)

Port-channel1 Yes (ldp) No Yes
Port-channel2 Yes (ldp) No Yes
Port-channel3 Yes (ldp) No Yes
Anyone have any ideas? This has been working for over a month now and all other
routers are up and using LDP successfully. In fact the other GSR this is
connected to is a carbon-copy, bar IP addresses
