Description (partial)

Multicast traffic stops forwarding to some CPE / modems following a PRE switchover event. The multicast database entries reflect an invalid forwarding interface for multicast traffic when compared to the modems primary forward interfaces reported in "show cable modem" output.

The issue is observed with multicast traffic after a PRE switchover event (such as OIR, crash, or CLI switchover).
