Configuring IP Multicast Routing
Configuring Static Traffic Forwarding with SSM Mapping
Use static traffic forwarding with SSM mapping to statically forward SSM traffic for certain groups. When static traffic
forwarding with SSM mapping is configured, the last hop router uses Domain Name System (DNS)-based SSM mapping
to determine the sources associated with a group. The resulting (S, G) channels are then statically forwarded.

DETAILED STEPS
Command
1. configure terminal
2. interface type number
3. ip igmp static-group
group-address source ssm-map
4. show running-config
5. copy running-config

EXAMPLE
The following example shows how to configure group address 239.1.2.1 to use SSM mapping for statically forwarded
groups on Ethernet interface 0:
interface ethernet 0
ip igmp static-group 239.1.2.1 source ssm-map
Configuring DNS-Based SSM Mapping, page
Purpose
Enter global configuration mode.
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.
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.
Verify your entries.
(Optional) Save your entries in the configuration file.
