The page includes the following fields:
• VLAN ID
• Querier
the case where there is more than one multicast router on a sub network, one
router is elected as the 'queried'. This router then keeps track of the membership
of the multicast groups that have active members. The information received from
IGMP is then used to determine if multicast packets should be forwarded to a
given sub network or not. The router can check, using IGMP, to see if there is at
least one member of a multicast group on a given subnet work. If there are no
members on a sub network, packets will not be forwarded to that sub network.
Enabled is the default value.
