3. Configure a static RP for IPv6
PIM-SM.
static-rp ipv6-rp-address
[ acl6-number ] [ preferred ]
No static RP by default.
CAUTION:
To enable a static RP to work normally, you must perform this configuration on all routers in the IPv6
PIM-SM domain and specify the same RP address.
Configuring a C-RP
In an IPv6 PIM-SM 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 you to configure C-RPs on backbone
routers.
To guard against C-RP spoofing, you need to configure a legal C-RP address range and the range of IPv6
multicast groups to be served on the BSR. In addition, because every C-BSR has a chance to become the
BSR, you need to configure the same filtering policy on all C-BSRs in the IPv6 PIM-SM domain.

3. Configure an interface to be a
C-RP for IPv6 PIM-SM.
c-rp ipv6-address [ { group-policy
acl6-number | scope scope-id } |
priority priority | holdtime

No C-RPs are configured by
default.
4. Configure a legal C-RP
address range and the range
of IPv6 multicast groups to be
served.
crp-policy acl6-number
Optional.
No restrictions by default.
NOTE:
When you configure a C-RP, ensure a relatively large bandwidth between this C-RP and the other
devices in the IPv6 PIM-SM domain.
An RP can serve multiple IPv6 multicast groups or all IPv6 multicast
g
roups. Only one RP can forward
IPv6 multicast traffic for an IPv6 multicast group at a moment.
Enabling embedded RP
With the embedded RP feature enabled, the router can resolve the RP address directly from the IPv6
multicast group address of an IPv6 multicast packets. This RP can replace the statically configured RP or
