Fix Recommendation

Configure the DR on a global or interface basis to limit the number of mroute states resulting from IGMP or MLD membership reports.

Check Contents

Review the DR configuration to verify that it is limiting the number of mroute states via IGMP or MLD.

If the DR is not limiting multicast join requests via IGMP or MLD, this is a finding.

Note: If both global and per-interface state limiters are configured, the limits configured for per-interface state limiters are still enforced but are constrained by the global limit.
