Chapter 15 Configuring Resilient Packet Ring on the ML-Series Card
Delete an ML-Series Card from an RPR
Step 23
Use a test set to verify that Ethernet connectivity exists on the RPR.
Step 24
Monitor Ethernet traffic and routing tables for at least one hour after the node insertion.
Stop. You have completed this procedure.
Delete an ML-Series Card from an RPR
An existing RPR might need an ML-Series card deleted. This can be done without taking down data
traffic due to the RPR wrapping capability and ring architecture.
The following example has a three-node RPR with three STS circuits connecting the ML-Series cards.
Two circuits will be deleted. The 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 deleted and a new STS circuit is created between
the two remaining cards.
Figure 15-9 shows the existing three-node RPR with all three STS circuits and spans. Figure 15-10
shows the RPR after the third node, circuits, and spans are deleted and the new STS circuit and span are
added.
