DESCRIPTION
IGMP/MLD Configuration
Default Version
Enter the version of IGMP (1~3) and MLD (1~2) that you want the VMG to use on the WAN.
Query Interval
Enter the number of seconds the VMG sends a query message to hosts to get the group
membership information.
Query Response
Interval
Enter the maximum number of seconds the VMG can wait for receiving a General Query
message. Multicast routers use general queries to learn which multicast groups have members.
Last Member
Query Interval
Enter the maximum number of seconds the VMG can wait for receiving a response to a Group-
Specific Query message. Multicast routers use group-specific queries to learn whether any
member remains in a specific multicast group.
Robustness
Value
Enter the number of times (1~7) the VMG can resend a packet if packet loss occurs due to
network congestion.
Maximum
Multicast
Groups
Enter a number to limit the number of multicast groups an interface on the VMG is allowed to
join. Once a multicast member is registered in the specified number of multicast groups, any
new IGMP or MLD join report frames are dropped by the interface.
