Query Response
Interval
Enter the maximum number of seconds the Zyxel Device can wait for receiving a General Query
message. Multicast routers use general queries to learn which multicast groups have members.
Last Member

Enter the maximum number of seconds the Zyxel Device 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 Zyxel Device 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 Zyxel Device 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.
Maximum
Multicast Data
Sources(for
IGMPv3)
Enter a number to limit the number of multicast data sources (1-24) a multicast group is allowed

change) especially for IPTV applications.
