Configuring the SSM
Group Range
Before configuring PIM-SSM, complete the following task:
Configure any unicast routing protocol so that all devices in the domain are
■
interoperable at the network layer.
Before configuring PIM-SSM, prepare the following data:
The SSM group range
■
The SSM model is implemented based on some subsets of PIM-SM. Therefore, a
router is PIM-SSM capable after you enable PIM-SM on it.
When deploying a PIM-SM domain, you are recommended to enable PIM-SM on
all interfaces of non-border routers (border routers are PIM-enabled routers
located on the boundary of BSR admin-scope regions).
Enabling PIM-SM globally in the public instance
Follow these steps to enable PIM-SM globally in the public instance:
To do...
Enter system view
Enable IP multicast routing
Enter interface view
Enable PIM-SM
Enabling PIM-SM in a VPN instance
Follow these steps to enable PIM-SM in a VPN instance:
To do...
Enter system view
Create a VPN instance and
enter VPN instance view
Configure a
route-distinguisher
(RD) for the VPN instance
Enable IP multicast routing
Enter interface view
Enable PIM-SM
CAUTION: All the interfaces in the same VPN instance on the same device must
work in the same PIM mode.
As for whether the information from a multicast source is delivered to the
receivers based on the PIM-SSM model or the PIM-SM model, this depends on
