SRRP Instance

The SRRP instance uses the received information to verify provisioning and obtain operational
status of the SRRP instance on the neighboring router.

SRRP Instance MCS Key
The SRRP instance MCS key ties the received MCS information to the local SRRP instance with
the same MCS key. If the received key does not match an existing SRRP instance, the MCS
information associated with the key is ignored. Once an SRRP instance is created and mapped to
an MCS peering, the SRRP instance evaluates received information with the same MCS key to
verify it corresponds to the same peering. If the received MCS key is on a different peering than
the local MCS key an SRRP peering mismatch event is generated detailing the SRRP instance ID,
the IP address of the peering the MCS key is received on and the IP address to which the local
MCS key is mapped. If the peering association mismatch is corrected, an SRRP peering mismatch
clear event is generated.
