Symptoms: When you change the MTU on a serial interface, the standby Route Processor (RP)
generates tracebacks, enters the STANDBY COLD-CONFIG state, and reboots.

a lesser value.

cef command.

Release 12.0(31)S, that functions as a PE router, and that has L2 transport VCs configured.

Symptoms: A router may take a very long time to establish LDP sessions with its peers and advertise
its label bindings. In some cases, the LDP sessions may flap.

a large number (greater than 250) of LDP neighbors and several thousand label bindings to advertise.
