Description (partial)

Crash of both active and standby ESP. Applies to ESP80, 100, and 200.

Updating the bandwidth of an active MFR bundle member-link. A bandwidth update will be sent from the RP to the FP if the FMAN-RP and FMAN-FP have different bandwidth values for the same link. This occurs immediately after boot if the startup-config has MFR member-links configured with FRF.12 fragmentation (active RP and standby RP will boot with different bandwidths, so that on switchover the standby RP will send a bandwidth update to the FP). Other situations that can lead to the bandwidth mismatch include adding/removing links to an MFR bundle with FRF.12 enabled and adding/removing FRF.12 from a main MFR interface prior to performing a switchover.
