Symptom: The router standby RSP displays an ether_efp_cfg_message_unmarshal_ error message
and crashes.
Conditions: Occurs under the following conditions:
–
The router has an 8 port Gigabit Ethernet interface module (IM)
–
The IM is configured with a service instance
–
The service instance has an xconnect and bridge domain interface (BDI) configuration
–
You perform an soft OIR (reset) on the IM while the standby RSP is booting
Workaround: Wait for the standby RSP to boot before resetting the IM.

Symptom: The router drops traffic on an EFP interface after you perform a stateful switchover
(SSO).
Conditions: Occurs under the following conditions:
–
You boot the standby RSP
–
The router configuration contains an EFP interface on a Gigabit Ethernet port and a bridge
domain interface in a down state.
–
After the router reaches an SSO state, you issue a no shutdown command on the peer router to
bring the EFP interface up.
