No static RP by default.
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 that you 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.
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.

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 hold-interval |

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.
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
the RP dynamically calculated based on the BSR mechanism. Therefore, the DR does not need to identify
the RP address beforehand.
Perform this configuration on all routers in the IPv6 PIM-SM domain.
