Use this procedure to configure IGMP router alert on a VLAN. The router alert feature instructs the router to drop control packets that do not have the router-alert flag in the IP header.
This procedure also allows you to configure IGMP snooping and proxy.
Attention With IGMP snoop, the QueryInterval, Robustness, and Version values must be the same as those configured on the interface (VLAN) of the multicast router (IGMP querier). |
Attention To maximize your network performance, Nortel recommends that you set the router alert parameter according to the version of IGMP currently in use:
|
IGMP snoop, proxy, and router alert are all disabled by default.
