Description: vRtrIgmpIfGroupCompatMode is used in order for routers to be compatible with older version routers. IGMPv3 hosts MUST operate in version 1 and version 2 compatibility modes. IGMPv3 hosts MUST keep state per local interface regarding the compatibility mode of each attached network. A host's compatibility mode is determined from the Host Compatibility Mode variable which can be in one of three states: IGMPv1, IGMPv2 or IGMPv3. This variable is kept per interface and is dependent on the version of General Queries heard on that interface as well as the Older Version Querier Present timers for the interface.
What is vRtrIgmpIfGroupCompatMode?
The IGMP compatibility mode (v1, v2, or v3) the router is currently operating in for this group on the interface, derived from the version of General Queries heard and the older-version-querier-present timers, so an IGMPv3-capable router can still interoperate with legacy hosts.
