IPv4 Access Control Lists (ACLs)
Configuring Extended ACLs
Additional Option for IGMP. This option 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. (For a summary of the extended ACL
syntax options, refer to table on page 10-59.)
Syntax: 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, beginning on page 10-72.
