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.

set protocols igmp interface <name>.<logical unit> group-limit <1..32767>
set protocols mld interface <name>.<logical unit> group-limit <1..32767>

Check Contents

Review the DR configuration to verify that it is limiting the number of mroute states via IGMP or MLD. Verify the group-limit parameter is appropriate for the target network.

[edit protocols]
igmp {
interface <name>.<logical unit> {
group-limit <1..32767>;
}
}
mld {
interface <name>.<logical unit> {
group-limit <1..32767>;
}
}

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