Enabling Bidir-Pim; Configuring An Rp - H3C S5500-EI Configuration Manual

Step
7. Enable PIM-SM.

Enabling BIDIR-PIM

Perform this configuration on all routers in the BIDIR-PIM domain.
To enable BIDIR-PIM:
Step
1. Enter system view.
2. Enter public network PIM view
or VPN instance PIM view.
3. Enable BIDIR-PIM.

Configuring an RP

An RP can be manually configured or dynamically elected through the BSR mechanism. For a large PIM
network, static RP configuration is a tedious job. Generally, static RP configuration is just used as a
backup means for the dynamic RP election mechanism to enhance the robustness and operation
manageability of a multicast network.
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.
Configuring a static RP
If only one dynamic RP exists in a network, manually configuring a static RP can avoid communication
interruption because of single-point failures and avoid frequent message exchange between C-RPs and
the BSR.
In BIDIR-PIM, a static RP can be specified with a virtual IP address. For example, if the IP addresses of the
interfaces at the two ends of a link are 10.1.1.1/24 and 10.1.1.2/24, you can specify a virtual IP address,
like 10.1.1.100/24, for the static RP. As a result, the link becomes an RPL.
To make a static RP to work normally, you must perform this configuration on all routers in the BIDIR-PIM
domain and specify the same RP address.
To configure a static RP:
Step
1. Enter system view.
