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

Purpose
(Optional) Enable DNS-based SSM mapping.
By default, the ip igmp ssm-map command enables DNS-based SSM
mapping. Only the no form of this command is saved to the running
configuration.
Use this command to re-enable DNS-based SSM mapping if
Note
DNS-based SSM mapping is disabled.
(Optional) Change the domain prefix used by the switch for DNS-based
SSM mapping.
By default, the switch uses the ip-addr.arpa domain prefix.
Specify the address of one or more name servers to use for name and
address resolution.
—
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
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.
