Context
This configuration becomes valid only after the reset multicast forwarding-table command is
used. Multicast services are interrupted after you run the reset multicast forwarding-table

9.6.4 Checking the Configuration

After control parameters for the multicast forwarding table are configured, you can check
information about the multicast routing table to ensure normal running of the multicast network.
Procedure

9.7 Maintaining the Multicast Policy

Maintaining IPv4 multicast routing management involves testing multicast routing, checking
the RPF path and multicast path, clearing multicast forwarding and routing entries, and
monitoring multicast routing and forwarding.

9.7.1 Testing Multicast Routing

When a fault occurs during multicast data transmission, you can run the ping command to check
the RPF path and multicast path.
