Configuring Static Traffic Forwarding with SSM Mapping
Use static traffic forwarding with SSM mapping to statically forward SSM traffic for certain groups.
Beginning in privileged EXEC mode, follow these steps to configure static traffic forwarding with SSM
mapping:
Monitoring SSM Mapping
Use the privileged EXEC commands in Table 33-4 to monitor SSM mapping.

Command Purpose
Step 1
configure terminal Enter global configuration mode.
Step 2
interface type number Select an interface on which to statically forward traffic for a multicast
group using SSM mapping, and enter interface configuration mode.
Note Static forwarding of traffic with SSM mapping works with either
DNS-based SSM mapping or statically configured SSM
mapping.
Step 3
ip igmp static-group group-address
source ssm-map
Configure SSM mapping to statically forward a (S, G) channel from the
interface.
Use this command if you want to statically forward SSM traffic for
certain groups. Use DNS-based SSM mapping to determine the source
addresses of the channels.
Step 4
show running-config Verify your entries.
Step 5
copy running-config startup-config (Optional) Save your entries in the configuration file.
