CAUTION:
In an IPv6 PIM network, if both IPv6 PIM-SM and IPv6 BIDIR-PIM are enabled, do not configure the
same RP to serve IPv6 PIM-SM and IPv6 BIDIR-PIM simultaneously to avoid IPv6 PIM routing table
errors.
Configuring a static RP
If only one dynamic RP exists in a network, configuring a static RP can avoid communication interruption
due to single-point failures and avoid frequent message exchange between C-RPs and the BSR.
Perform this configuration on all routers in the IPv6 BIDIR-PIM domain.
Follow these steps to configure a static RP:

Configure a static RP for IPv6
BIDIR-PIM
static-rp ipv6-rp-address [ acl6-
number ] [ preferred ] bidir
Required
No static RP by default
CAUTION:
You must perform static RP configuration on all routers in the IPv6 PIM-SM domain and specify the
same RP address.
NOTE:
In IPv6 BIDIR-PIM, a static RP can be specified with a virtual IPv6 address. For example, if the IPv6
addresses of the interfaces at the two ends of a link are 1001::1/64 and 1001::2/64, specify a virtual
IPv6 address, like 1001::100/64, for the static RP. As a result, the link becomes an RPL.
Configuring a C-RP
In an IPv6 BIDIR-PIM domain, you can configure routers that intend to become the RP as C-RPs. The BSR
collects the C-RP information by receiving the C-RP-Adv messages from C-RPs or auto-RP announcements
from other routers and organizes the information into an RP-set, which is flooded throughout the entire
network. Then, the other routers in the network calculate the mappings between specific group ranges
and the corresponding RPs based on the RP-set. HP recommends that you configure C-RPs on backbone
routers.
To guard against C-RP spoofing, configure a legal C-RP address range and the range of multicast groups
to be served on the BSR. In addition, because every C-BSR has a chance to become the BSR, you must
configure the same filtering policy on all C-BSRs in the IPv6 BIDIR-PIM domain.
