Configuring IP Multicast Routing
Configuring Static SSM Mapping
Beginning in privileged EXEC mode, follow these steps to configure static SSM mapping:
For additional information on SSM mapping, see the “Source Specific Multicast (SSM) Mapping”
chapter of the Cisco IOS IP Multicast Configuration Guide, Release 12.4T.
Configuring DNS-Based SSM Mapping
To configure DNS-based SSM mapping, you need to create a DNS server zone or add records to an
existing zone. If the routers that are using DNS-based SSM mapping are also using DNS for other
purposes, you should use a normally configured DNS server. If DNS-based SSM mapping is the only
DNS implementation being used on the router, you can configure a false DNS setup with an empty root
zone or a root zone that points back to itself.
Beginning in privileged EXEC mode, follow these steps to configure DNS-based SSM mapping:
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
ip igmp ssm-map enable Enable SSM mapping for groups in the configured SSM range.
Note By default, this command enables DNS-based SSM mapping.
Step 3
no ip igmp ssm-map query dns (Optional) Disable DNS-based SSM mapping.
Note Disable DNS-based SSM mapping if you only want to rely on
static SSM mapping. By default, the ip igmp ssm-map global
configuration command enables DNS-based SSM mapping.
Step 4
ip igmp ssm-map static access-list
source-address
Configure static SSM mapping.
The ACL supplied for access-list defines the groups to be mapped to the
source IP address entered for the source-address.
Note You can configure additional static SSM mappings. If additional
SSM mappings are configured and the router receives an
IGMPv1 or IGMPv2 membership report for a group in the SSM
range, the switch determines the source addresses associated
with the group by using each configured ip igmp ssm-map
static command. The switch associates up to 20 sources per
group.
Step 5
Repeat Step 4 to configure additional
static SSM mappings, if required.

Step 6
end Return to privileged EXEC mode.
Step 7
show running-config Verify your entries.
Step 8
copy running-config startup-config (Optional) Save your entries in the configuration file.
Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
ip igmp ssm-map enable Enable SSM mapping for groups in a configured SSM range.
