Enabled

periodically check the multicast group for members that are no longer active. In 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.
