the SSM group range. All PIM-SM-enabled interfaces assume the PIM-SSM model for multicast groups
within this address range.
Configuration guidelines
•
Perform the following configuration on all routers in the PIM-SSM domain.
Make sure the same SSM group range is configured on all routers in the entire domain. Otherwise,
•
multicast information cannot be delivered through the SSM model.
•
When a member of a multicast group in the SSM group range sends an IGMPv1 or IGMPv2 report
message, the device does not trigger a (*, G) join.
Configuration procedure
To configure an SSM multicast group range:
Step
1.
Enter system view.
2.
Enter public network PIM view
or VPN instance PIM view.
3.
Configure the SSM group
range.
Configuring common PIM features
For the configuration tasks in this section, the following rules apply:
The configurations made in PIM view are effective on all interfaces. The configurations made in
•
interface view are effective only on the current interface.
A configuration made in interface view always has priority over the same configuration made in
•
PIM, regardless of the configuration sequence.

Configuration prerequisites
Before you configure common PIM features, complete the following tasks:

•
network layer.
•
Configure PIM-DM, or PIM-SM, or PIM-SSM.
