Configuring IPv6 BIDIR-PIM

This section describes how to configure IPv6 BIDIR-PIM.
Configuration restrictions and guidelines
When you configure IPv6 BIDIR-PIM, follow these restrictions and guidelines:
•
IPv6 BIDIR-PIM does not support IPv6 multicast forwarding over a GRE tunnel.
•
IPv6 BIDIR-PIM is not supported on Layer 3 Ethernet interfaces or Layer 3 aggregate groups.
To ensure correct multicast forwarding in an IPv6 BIDIR-PIM domain, do not use Layer 3
Ethernet interfaces or Layer 3 aggregate interfaces as multicast forwarding interfaces. For
more information about Layer 3 Ethernet interfaces and Layer 3 aggregate groups, see
Interface Configuration Guide and Layer 2—LAN Switching Configuration Guide, respectively.

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 domain.
IMPORTANT:
All interfaces on a device must be enabled with the same IPv6 PIM mode.
Enabling IPv6 BIDIR-PIM
Configuring an RP:
Setting the maximum number of IPv6 BIDIR-PIM RPs
Configuring a C-BSR
Configuring an IPv6 PIM domain border
Disabling BSM semantic fragmentation
Configuring common IPv6 PIM features
Command
spt-switch-threshold
{ immediacy | infinity }
[ group-policy acl6-number ]
323
Remarks
By default, the switch immediately
triggers the switchover to SPT
after receiving the first multicast
packet.
Remarks
N/A
You must configure a static
RP, a C-RP, or both in an
IPv6 BIDIR-PIM domain.
Skip the task of configuring a
BSR on an IPv6 network
without C-RPs.
