Compatibility
mode
Specifies the IGMP mode. This 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.
V1 host expires
The time remaining until the local router will assume that there are
no longer any IGMP Version 1 members on the IP subnet attached to
this interface. Upon hearing any IGMPv1 membership report, this
value is reset to the group membership timer. While this time remain-
ing is non-zero, the local router ignores any IGMPv2 leave messages
for this group that it receives on this interface.
V2 host expires
The time remaining until the local router will assume that there are
no longer any IGMP Version 2 members on the IP subnet attached to
this interface. Upon hearing any IGMPv2 membership report, this
value is reset to the group membership timer. While this time remain-
ing is non-zero, the local router ignores any IGMPv3 leave messages
for this group that it receives on this interface.
