50An Introduction to IP Routing Protocols

•The snooping ﬁeld must be enabled for the proxy ﬁeld to have any valid meaning.

•Static router ports are conﬁgured per VLAN and per IGMP Version.

Note: Because IGMP snooping is set up per VLAN, all IGMP changes are implemented according to the VLAN conﬁguration for the speciﬁed ports.
