igmpInterfaceQuerier
Module: IGMP-STD-MIB
OID (symbolic): IGMP-STD-MIB::igmpInterfaceQuerier
OID (numeric): 1.3.6.1.2.1.85.1.1.1.5
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-only
Description: The address of the IGMP Querier on the IP subnet to which
this interface is attached.
What is igmpInterfaceQuerier?
A read-only IP address reporting which router is currently acting as the IGMP Querier on this interface's subnet. Only one router per subnet actively sends IGMP queries at a time, normally the one with the lowest IP, so this tells an admin which router is currently responsible for that role, useful when troubleshooting multicast group membership tracking. If this object doesn't show the expected router's IP, an admin would investigate why querier election chose a different router, possibly due to an IP addressing issue.
Examples
