Configuring IPv6 PIM-SSM 1257
Before configuring IPv6 PIM-SSM, prepare the following data:
■
The IPv6 SSM group range
Enabling IPv6 PIM-SM The SSM model is implemented based on some subsets of IPv6 PIM-SM. Therefore,
a router is IPv6 PIM-SSM capable after you enable IPv6 PIM-SM on it.
When deploying an IPv6 PIM-SM domain, you are recommended to enable IPv6
PIM-SM on all interfaces of non-border routers (border routers are IPv6 PIM routers
located on the boundary of BSR admin-scope regions).
Follow these steps to enable IPv6 PIM-SSM:
c
CAUTION: All the interfaces of the same device must work in the same IPv6 PIM
mode.
Configuring the IPv6
SSM Group Range
As for whether the information from an IPv6 multicast source is delivered to the
receivers based on the IPv6 PIM-SSM model or the IPv6 PIM-SM model, this
depends on whether the group address in the (S, G) channel subscribed by the
receivers falls in the IPv6 PIM-SSM group range. All IPv6 PIM-SM-enabled
interfaces assume that IPv6 multicast groups within this address range are using
the IPv6 SSM model.
Follow these steps to configure the IPv6 SSM group range:
n
The commands introduced in this section are to be configured on all routers in the
IPv6 PIM domain.

CAUTION:
■
Make sure that the same IPv6 SSM group range is configured on all routers in
the entire PIM-SSM domain. Otherwise, IPv6 multicast data cannot be delivered
through the IPv6 SSM model.
