Configuration prerequisites

Before you configure BIDIR-PIM, configure a unicast routing protocol so that all devices in the
domain can interoperate at the network layer.

Enabling BIDIR-PIM

Because BIDIR-PIM is implemented on the basis of PIM-SM, you must enable PIM-SM before you
enable BIDIR-PIM. As a best practice, enable PIM-SM on all non-border interfaces of routers when
you deploy a BIDIR-PIM domain.
IMPORTANT:
All interfaces on a device must be enabled with the same PIM mode.
To enable BIDIR-PIM:
Step
Enter system view.
1.
Enable IP multicast routing
2.
and enter MRIB view.
Return to system view.
3.
Enter interface view.
4.
Enable PIM-SM.
5.
Return to system view.
6.
Enter PIM view.
7.
Enable BIDIR-PIM.
8.

Configuring an RP

CAUTION:
When both PIM-SM and BIDIR-PIM run on the PIM network, do not use the same RP to provide
services for PIM-SM and BIDIR-PIM. Otherwise, exceptions might occur to the PIM routing
table.
An RP can provide services for multiple or all multicast groups. However, only one RP can forward
multicast traffic for a multicast group at a time.
An RP can be manually configured or dynamically elected through the BSR mechanism. For a
large-scaled 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 a multicast network.
