View This command can be used in the following views:
■ PIM view
Description 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.
