Brocade Communications Systems Upgrade Pef IPMC5000PEF IPMC5000PEF User Manual

Theacl-id variable specifies the ACL ID that contains the group multicast address.

The source-address variable specifies the source address that you want to map to the group multicast
address specified in the ACL.

The no option is used to delete a previously configured SSM map.

Example configuration

In the following example configuration, one extended ACL and two standard ACLs are defined with
group multicast addresses. The ip igmp ssm-map commands are configured to map the ACLs to
source addresses and to enable the feature on the router.

device(config)# access-list 20 host 239.1.1.1

device(config)# access-list 20 permit 224.1.1.0 0.0.0.225

device(config)# access-list 100 permit any host 232.1.1.1

device(config)# ip igmp ssm-map 20 1.1.1.1

device(config)# ip igmp ssm-map 20 2.2.2.2

device(config)# ip igmp ssm-map 100 1.1.1.1

device(config)# ip igmp ssm-map enable
