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 deploying an IPv6 PIM-SM domain, you
are recommended to enable IPv6 PIM-SM on all non-border interfaces of the routers.
Follow these steps to enable IPv6 PIM-SM:
To do...
Use the command...
Remarks
Enter system view

—
Enable IPv6 multicast routing
multicast ipv6 routing-enable
Required
Disable by default
Enter interface view

—
Enable IPv6 PIM-SM
pim ipv6 sm
Required
Disabled by default
All the interfaces of the same device must work in the same IPv6 PIM mode.
For details about the multicast ipv6 routing-table command, see IPv6 Multicast Routing and
Forwarding Commands in the IP Multicast Volume.
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 means for the dynamic RP election mechanism to enhance the robustness and operation
manageability of a multicast network.
Configuring a static RP
If there is only one dynamic RP in a network, manually configuring a static RP can avoid communication
interruption due to single-point failures and avoid frequent message exchange between C-RPs and the
BSR.
Perform the following configuration on all the routers in the IPv6 PIM-SM domain.
Follow these steps to configure a static RP:
To do…
Use the command…
