Enabling IPv6 PIM-SM
With IPv6 PIM-SM enabled, a router sends hello messages periodically to discover IPv6 PIM neighbors
and processes messages from the IPv6 PIM neighbors. When you deploy an IPv6 PIM-SM domain,
enable IPv6 PIM-SM on all non-border interfaces of the routers.

Configuring an RP
An RP can be manually configured or dynamically elected through the BSR mechanism. For a large IPv6
PIM network, static RP configuration is a tedious job. Generally, static RP configuration is just a backup
method for the dynamic RP election mechanism to enhance the robustness and operation manageability
of a multicast network.
Configuring a static RP
If only one dynamic RP exists in a network, manually configuring a static RP can avoid communication
interruption because of single-point failures. It can also avoid frequent message exchange between C-RPs
and the BSR.
To enable a static RP to work normally, you must perform this configuration on all routers in the IPv6
PIM-SM domain and specify the same RP address.
Perform the following configuration on all the routers in the IPv6 PIM-SM domain.
To configure a static RP:
