Configuring IPv6 PIM-SM
This section describes how to configure IPv6 PIM-SM.
IPv6 PIM-SM configuration task list
(Required.) Enabling IPv6 PIM-SM N/A
(Required.) Configuring an RP:
• Configuring a static RP
• Configuring a C-RP
• (Optional.) Configuring Anycast RP
You must configure a static RP, a C-RP, or both
in an IPv6 PIM-SM domain.
Configuring a BSR:
• (Required.) Configuring a C-BSR
• (Optional)
Disabling BSM forwarding out of
incoming interfaces
• (Optional.) Configuring an IPv6 PIM domain border
• (Optional.) Disabling BSM semantic fragmentation
Skip the task of configuring a BSR on a network
without C-RPs.
(Optional.) Configuring IPv6 multicast source registration N/A
(Optional.) Configuring the switchover to SPT N/A
(Optional.) Configuring common IPv6 PIM features N/A
Configuration prerequisites
Before you configure IPv6 PIM-SM, configure an IPv6 unicast routing protocol so that all devices in
the domain can interoperate at the network layer.
Enabling IPv6 PIM-SM
Enable IPv6 multicast routing before configuring IPv6 PIM.
With IPv6 PIM-SM enabled on interfaces, routers can establish IPv6 PIM neighbor relationship and
process IPv6 PIM messages from their IPv6 PIM neighbors. As a best practice, enable IPv6 PIM-SM
on all non-border interfaces on routers when you deploy an IPv6 PIM-SM domain.
IMPORTANT:
All the interfaces on the same router must operate in the same IPv6 PIM mode in the public network
or the same VPN instance.
To enable IPv6 PIM-SM:
1. Enter system view.
