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.
Configuring a static RP
If only one dynamic RP exists on a network, you can configure a static RP to avoid communication
interruption caused by single-point failures. The static RP also avoids bandwidth waste due to frequent
message exchange between C-RPs and the BSR. The static RP configuration must be the same on all
routers in the BIDIR-PIM domain.
In BIDIR-PIM, a static RP can be specified with an unassigned IP address. This address must be on the
same subnet with the link on which the static RP is configured. 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 assign 10.1.1.100/24 to the
static RP. As a result, the link becomes an RPL.
To configure a static RP:
Step
1. Enter system view.
2. Enter PIM view.
3. Configure a static RP for
BIDIR-PIM.
Configuring a C-RP
IMPORTANT:
When you configure a C-RP, reserve a large bandwidth between the C-RP and other devices in the
BIDIR-PIM domain.
In a BIDIR-PIM domain, if you want a router to become the RP, you can configure the router as a C-RP. The
BSR collects the C-RP information according to the received advertisement messages from C-RPs or the
auto-RP announcements from other routers. Then, it organizes the C-RP information into the RP-set
information, which is flooded throughout the entire network. Then, the other routers in the network can
