Controlling IGMP traffic flow

This command is useful where it is necessary to permit some types of IGMP traffic and deny other types, instead of simply permitting or denying all types of IGMP traffic. That is, an ACE designed to permit or deny IGMP traffic can optionally include an IGMP packet type to permit or deny an individual type of IGMP packet while not addressing other IGMP traffic types in the same ACE. As an optional alternative, the ACE can include the name of an ICMP packet type.


access-list <100 - 199>

{<deny | permit>} igmp <src-ip> <dest-ip> [igmp-type]

The IGMP "type" criteria is identical to the criteria described for IGMP in named, extended ACLs. See Controlling IGMP traffic in extended ACLs.
