Verifying RPR-IEEE End-to-End Ethernet Connectivity

After successfully completing the procedures to provision an RPR-IEEE, you can test Ethernet
connectivity between the Ethernet access ports on the separate ML-Series cards. To do this, use your
standard Ethernet connectivity testing.
Understanding Redundant Interconnect
Ring interconnect (RI) is a mechanism to interconnect RPRs, both RPR-IEEE and Cisco proprietary
RPR, for protection from failure. It does this through redundant pairs of back-to-back G igabit Ethernet
connections that bridge RPR networks. One connection is the active node and the other is the standby
node. During a failure of the active node, link, or card, the detection of the failure triggers a switchover
to the standby node. Figure 26-8 illustrates an example of RPR RI.
