What is rlMgmdRouterInterfaceExtNumIgmpV1Msgs?
This read-only Unsigned32 counts IGMPv1 messages received on this interface, including both valid and invalid ones. It gives the admin visibility into whether any hosts on the segment are still using the oldest IGMP version. For example, an unexpectedly high count here on a network standardized on IGMPv3 could reveal a legacy host still running an outdated IGMP stack.
