BSR 64000 Configuration and Management Guide
8-20
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 <n>
where:
n is the query response interval from 1 to 25 seconds.
Configuring the BSR as a Static Multicast Group Member
An interface is configured with a static multicast group for the following reasons:
• 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.
Use the ip igmp static-group command in Interface Configuration mode to configure
the BSR to become a statically connected multicast group member, as shown below:
MOT(config-if)#ip igmp static-group <ip-address>
where:
ip-address is the multicast group IP address for the BSR.
Managing IP Multicast Routing on the BSR
The following sections are used to manage multicast routing on the BSR:
• Configuring an IP Multicast Static Route
• Changing the Distance for a Unicast Multicast Route
• Changing the Distance for a Static Multicast Route
• Clearing IP Multicast Information
