6. Bind the interface with the
VPN instance.
ip binding vpn-instance

By default, an interface belongs to
the public network, and is not
bound with any VPN instance.

command, see MPLS Command

Enabling BIDIR-PIM
Perform this configuration on all routers in the BIDIR-PIM domain.

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 method 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 serve 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 due to 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 operate correctly, you must perform this configuration on all routers in the
BIDIR-PIM domain and specify the same RP address.
