Enabling Bidir-Pim - HP A8800 Configuration Manual

For more information about the ip vpn-instance, route-distinguisher, and ip binding vpn-instance
commands, see MPLS Command Reference.

Enabling BIDIR-PIM

If BIDIR-PIM is enabled on the public network or in a VPN, the tunnel interfaces on the public network or
in the VPN do not support Layer 3 multicasting.
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 a backup means
for the dynamic RP election mechanism to enhance the robustness and operation manageability of a
multicast network.
CAUTION:
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 there is only one dynamic RP 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.
You must perform static RP configuration on all routers in the PIM-SM domain and specify the same RP
address.
Perform this configuration on all routers in the BIDIR-PIM domain.
To configure a static RP:
Step
1. Enter system view.
2. Enter public network PIM view
or VPN instance PIM view.
3. Configure a static RP for
BIDIR-PIM.
