Table 9-7. IGMP Interface Parameters
Allows you to...
turns off processing of IGMP leave messages when set to
disable. The default value is Enable.
Enter a time period between queries. The default value
is 125 seconds.
Enter a time (in seconds) to wait for a response from a
host after a query is sent. If no response is received
within this time, the host is removed from the group
table. The default value is 10 seconds.
Enter a time (in seconds) this interface should wait after
hearing a neighbor's query before assuming the role of
querier, if not already the querier. If no query is
received from a neighbor with a lower IP address in the
allotted time, this interface becomes the querier (IGMP
Version 2.0 only). The default value is 255 seconds.
Modify this field for any expected packet loss on a
subnet. If a subnet is expected to have more packet loss,
the Robustness Variable should be increased. The
Robustness Variable must not be set to 0 and should not be
set to 1. The default value is 2.

To modify an IGMP interface using the CLI, enter the following
command from interface mode:
(config-if:<interface>)# ip igmp <options>
Refer to the Command Reference Guide for the Avaya P550R, P580, P880,
and P882 Multiservice Switches, Version 5.3.1 for details about this
command.
Distance Vector Multicast Routing Protocol (DVMRP) uses IP
packets with protocol type 2 (IGMP) to exchange routing datagrams.
DVMRP enables multicast routers to exchange distance vector
updates that contain multicast flow lists and their corresponding
cost metrics. DVMRP may use tunneling between pairs of DVMRP
routers when traffic must pass through one or more intermediary
routers or gateways that do not implement DVMRP.This
implementation adheres to the specification for DVMRP V3.
