Configuring IP Multicast Routing

Configuring SSM

Beginning in privileged EXEC mode, follow these steps to configure SSM:
Command
Step 1 ip pim ssm [default | range access-list]
Step 2 interface type number
Step 3 ip pim {sparse-mode | sparse-dense-mode}
Step 4 ip igmp version 3
Step 5 end
Step 6 show running-config
Step 7
copy running-config startup-config

Monitoring SSM

Beginning in privileged EXEC mode, follow these steps to monitor SSM.
Command
Router# show ip igmp groups detail
Router# show ip mroute

Configuring Source Specific Multicast Mapping

The Source Specific Multicast (SSM) mapping feature supports SSM transition when supporting SSM
on the end system is impossible or unwanted due to administrative or technical reasons. You can use
SSM mapping to leverage SSM for video delivery to legacy STBs that do not support IGMPv3 or for
applications that do not use the IGMPv3 host stack.

Purpose
Define the SSM range of IP multicast addresses.
Select an interface that is connected to hosts on which
IGMPv3 can be enabled, and enter the interface configuration
mode.
Enable PIM on an interface. You must use either sparse mode
or sparse-dense mode.
Enable IGMPv3 on this interface. The default version of
IGMP is set to Version 2.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
Purpose
Display the (S, G) channel subscription through IGMPv3.
Display whether a multicast group supports SSM service or
whether a source-specific host report was received.
