Before You Begin
This task does not include the steps for configuring DNS-based SSM mapping. See the Configuring DNS-Based
SSM Mapping(CLI), on page 271 task for more information about configuring DNS-based SSM mapping.
SUMMARY STEPS
1.
enable
2.
configure terminal
3.
interface type number
4.
ip igmp static-group group-address source ssm-map
DETAILED STEPS
PurposeCommand or Action
Enables privileged EXEC mode.enable
Step 1
Example:
Router> enable
•
Enter your password if prompted.
Enters global configuration mode.configure terminal
Example:
Router# configure terminal
Step 2
Selects an interface on which to statically forward traffic for a multicast
group using SSM mapping and enters interface configuration mode.
interface type number
Example:
Router(config)# interface
gigabitethernet 1/0/0
Step 3
Static forwarding of traffic with SSM mapping works with
either DNS-based SSM mapping or statically-configured SSM
mapping.
Note
Configures SSM mapping to be used to statically forward a (S, G)
channel out of the interface.
ip igmp static-group group-address source
ssm-map
Step 4
Example:
Router(config-if)# ip igmp static-group
232.1.2.1 source ssm-map
•
Use this command if you want to statically forward SSM traffic
for certain groups, but you want to use DNS-based SSM mapping
to determine the source addresses of the channels.
