Configuring Igmp Snooping Querier; Configuring Igmp Snooping Mrouter - Brocade Communications Systems Converged Enhanced Ethernet 8000 Administrator's Manual

9. Optional: Activate the IGMP querier functionality with additional features.

Configuring IGMP snooping querier

If your multicast traffic is not routed because Protocol-Independent Multicast (PIM) and IGMP are
not configured, use the IGMP snooping querier in a VLAN.
IGMP snooping querier sends out IGMP queries to trigger IGMP responses from switches that wish
to receive IP multicast traffic. IGMP snooping listens for these responses to map the appropriate
forwarding addresses.
Refer to the CEE Command Reference for complete information about the commands in this
section.
To configure the IGMP snooping querier, use the following procedure from privileged EXEC mode.
1. Enter interface configuration mode.
2. Activate the default IGMP querier functionality for the VLAN.
3. Return to privileged EXEC mode.
4. Set the IGMP querier interval for the VLAN.
5. Set the last member query interval.
6. Set the Max Response Time (MRT).

Configuring IGMP snooping mrouter

To configure IGMP snooping mrouter, perform this task in global configuration mode.
1. Enter interface configuration mode for the VLAN port member.
2. Configure a the port member to be a multicast router interface.
