static-rp (PIM view)

Syntax static-rprp-address [ acl-number ] [ preferred ]

undo static-rp rp-address

View Public instance PIM view, VPN instance PIM view

Parameter rp-address: IP address of the static RP to be configured. This address must be a legal unicast IP address, rather than an address on the 127.0.0.0/8 segment.

acl-number: Basic ACL number, in the range of 2000 to 2999. If you provide this argument, the configured static RP will serve only those groups that pass the ACL filtering; otherwise, the configured static RP will serve the all-system group 224.0.0.0/4.

preferred: Specifies to give priority to the static RP if the static RP conflicts with the dynamic RP. If you do not include the preferred keyword in your command, the dynamic RP will be given priority, and the static RP takes effect on if no dynamic RP exists in the network or when the dynamic RP fails.

Description Use the static-rpcommand to configure a static RP.

Use the undo static-rpcommand to configure a static RP.

By default, no static RP is configured.

Note that:

■PIM-SM or PIM-DM cannot be enabled on an interface that serves as a static RP.

■When the ACL rule applied on a static RP changes, a new RP must be elected for all the multicast groups.

■You can configure multiple static RPs by using this command repeatedly. However, if you carry out this command multiple times and specify the same static RP address or reference the same ACL rule, the last configuration will override the previous one. If multiple static RPs have been configured for the same multicast group, the one with the highest IP address will be chosen to serve the multicast group.
