R211x-HP Flexfabric 11900 IP Multicast Command Reference

223
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 IPv6 PIM on an interface that acts as a static RP.
In an ACL, the source field specifies the IPv6 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 IPv6 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 commands, the most recent configuration takes
effect. If you configure multiple static RPs for the same IPv6 multicast group, the static RP with the highest
IPv6 address is used.
Examples
# On the public network, configure the interface with the IPv6 address of 2001::2 as a static RP for the
IPv6 multicast groups FF03::101/64, and give priority to this static RP when conflicts exist between static
and dynamic RPs.
