Add an ML-Series Card into a Cisco Proprietary RPR
An existing Cisco proprietary RPR might need an ML-Series card added. This can be done without
taking down data traffic due to the Cisco proprietary RPR wrapping capability and ring architecture. You
can add the ML-Series card in concert with the addition of the node containing the card into the
underlying SONET/SDH architecture. You can also add an ML-Series card to a node that is already part
of the SONET/SDH topology.
The following example has a two-node Cisco proprietary RPR with two STS circuits connecting the
ML-Series cards. One circuit will be deleted. The Cisco proprietary RPR will wrap traffic on the
remaining circuit with as little as a one ping loss. The third node and ML-Series card are then added in,
and the spans and circuits for this card are created.
