BSR 2000 Configuration and Management Guide

Changing the Maximum Query Response Time

IGMP Version 2 allows the maximum query response time advertised in IGMP
queries to be changed. The maximum query response time allows a router to quickly
detect that there are no more directly connected group members on a subnetwork.
Decreasing the value allows the BSR to prune groups quickly.
The query response interval is the maximum amount of time that can elapse between
when the querier router sends a host-query message and when it receives a response
from a host.
Use the ip igmp query-max-response-time command to change the query response
interval to change the burstiness of IGMP messages on the subnetwork. The query
response interval is 10 seconds by default.
MOT(config-if)# ip igmp query-max-response-time <1-255>
where:

Configuring the BSR as a Static Multicast Group Member

An interface is configured with a static multicast group for the following reasons:
Use the ip igmp static-group command in Interface Configuration mode to configure
the BSR to become a statically connected multicast group member:
MOT(config-if)# ip igmp static-group <A.B.C.D>
where:

Managing IP Multicast Routing on the BSR

The following sections are used to manage multicast routing on the BSR:
9-12
60-3600 is the time interval in seconds.
1-255 is the query response interval in tenths of a second.
Performance increases by allowing the BSR to forward multicast packets over the
interface to directly connected networks without processing the multicast packets.
A multicast group member is not associated with a specific network.
The host cannot report its multicast group membership using IGMP.
A.B.C.D is the multicast group IP address for the BSR.
