Purpose
Command or Action
These interfaces must have IP addresses assigned to them.
Static forwarding of traffic with SSM mapping works with either
DNS-based SSM mapping or statically configured SSM mapping.
Note
Configures SSM mapping to statically forward a (S, G) channel from the
interface.
ip igmp static-group group-address
source ssm-map
Step 4
Example:
Device(config-if)#
ip igmp
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.
static-group 239.1.2.1 source
ssm-map
Returns to privileged EXEC mode.
end
Example:
Device(config-if)#
