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.
acl-number: Specifies an IPv4 basic ACL by its number in the range of 2000 to 2999 to filter IPv4
multicast groups. The static RP is designated only to IPv4 multicast groups that pass the ACL filtering. If
you do not specify an ACL, or if you specify an ACL that does not exist or does not contain any valid rules,
the static RP is designated to all multicast groups 224.0.0.0/4.
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 this keyword is not
specified, the dynamic RP has priority, and 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
effect. If you configure multiple static RPs for the same multicast group, the static RP with the highest IP
address is used.
Examples
# On the public network, configure the interface with the IP address of 11.110.0.6 as a static RP for
multicast groups 225.1.1.0/24, and give priority to this static RP when conflicts exist between static and
dynamic RPs.
