Configuring common IPv6 PIM features
N/A
Configuration prerequisites
Before you configure IPv6 BIDIR-PIM, configure an IPv6 unicast routing protocol so that all devices
in the domain can interoperate at the network layer.
Enabling IPv6 BIDIR-PIM
Because IPv6 BIDIR-PIM is implemented on the basis of IPv6 PIM-SM, you must enable IPv6
PIM-SM before enabling IPv6 BIDIR-PIM. As a best practice, enable IPv6 PIM-SM on all non-border
interfaces of routers when you deploy an IPv6 BIDIR-PIM.
IMPORTANT:
All interfaces on a device must be enabled with the same IPv6 PIM mode.

Configuring an RP
CAUTION:
When both IPv6 PIM-SM and IPv6 BIDIR-PIM run on the IPv6 PIM network, do not use the same RP
to provide services for IPv6 PIM-SM and IPv6 BIDIR-PIM. Otherwise, exceptions might occur to the
IPv6 PIM routing table.
An RP can provide services for multiple or all IPv6 multicast groups. However, only one RP at a time
can forward IPv6 multicast traffic for an IPv6 multicast group.
An RP can be manually configured or dynamically elected through the BSR mechanism. For a
large-scaled IPv6 PIM network, configuring static RPs is a tedious job. Generally, static RPs are
backups for dynamic RPs to enhance the robustness and operational manageability on an IPv6
multicast network.
