Module: TIMETRA-MLD-MIB
OID (symbolic): TIMETRA-MLD-MIB::vRtrMldIfGroupCompatMode
OID (numeric): 1.3.6.1.4.1.6527.3.1.2.46.2.3.1.8
Node type: OBJECT-TYPE

Access: read-only
Description: The value of vRtrMldIfGroupCompatMode is used in order for routers to be compatible with older version routers. MLDv2 hosts MUST operate in version 1 and version 2 compatibility modes. MLDv2 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 two states: MLDv1 or MLDv2. 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 vRtrMldIfGroupCompatMode?
Reports which MLD version (v1 or v2) compatibility mode this interface is currently operating in for this group, kept per interface based on the version of General Queries heard and the Older-Version-Querier-Present timers, per RFC 3810's compatibility-mode rules. An admin checks this when troubleshooting why a group is behaving as if an older MLD version were in use, even though the interface is configured for MLDv2.
