Command Reference Guide Chapter 3 PIM Configuration Commands

Parameter
rp-address: Static RP address. This address must be valid unicast IP address and
cannot be configured as the address in 127 network segment.
acl-number: Number of basic ACL, used in controlling the multicast group range that
static RP serves. The value ranges from 2000 to 2999.
Description
Use the static-rp command to configure static RP.
Use the undo static-rp command to remove the configuration.
RP is the kernel router in multicast routing. If the dynamic RP elected through BSR
mechanism is invalid for some reason, static RP can be configured as backup of the
dynamic RP to improve robusticity of the network and operation management capability
of the multicast network.
All routers in the PIM domain should be configured with this command and be specified
with the same RP address. If the configured static RP address is the address of an UP
interface on the local device, the local device will act as static RP. PIM is not necessarily
enabled on the interface which acts as static RP.
If this command is configured but ACL is not specified, the static RP configured will
serve all the multicast groups. If ACL is specified, the static RP configured will only
serve the multicast group permitted by the ACL.
In the case that the RP elected through BSR mechanism is valid, static RP does not
take effect.
If this command is executed repeatedly, the new configuration will overwrite the
previous one.
Related command: display pim rp-info.
