Parameters
rp-address: Specifies the IP address of the static RP. This address must be a real, valid unicast IP address,
rather than an address on the 127.0.0.0/8 subnet. For a static RP serving BIDIR-PIM, you can specify a
virtual IP address.
acl-number: Specifies an IPv4 basic ACL number in the range of 2000 to 2999 to filter IPv4 multicast
groups. The command designates the static RP only to the multicast groups that the ACL permits. The
command designates the static RP to all multicast groups 224.0.0.0/4 when any of the following
conditions exists:
• You do not specify any ACL.
• The specified ACL does not exist.
• The specified ACL does not have any valid rules.
bidir: Specifies BIDIR-PIM to which the static RP is designated. If you do not specify this keyword, the PIM
mode is PIM-SM.
preferred: Gives priority to the static RP if the static RP and the dynamic RP exist at the same time in the
network. The dynamic RP takes effect only if no static RP exists in the network. If you do not specify this
keyword, the dynamic RP has priority. The static RP takes effect only if no dynamic RP exists in the network
or when the dynamic RP fails.
Usage guidelines
You do not need to enable PIM on an interface that acts as a static RP.
In an ACL, the source field specifies the multicast group range to which the static RP is designated. If you
specify a VPN instance in the ACL, the ACL does not take effect. The other optional parameters except
the time-range keyword and the fragment keyword are ignored.
When the ACL rules referenced by a static RP change, new RPs must be elected for all multicast groups.
You can configure multiple static RPs by using this command multiple times. However, if you specify the
same static RP address or reference the same ACL in the command, the most recent configuration takes
