3. Configure a static RP for IPv6
PIM-SM.

By default, no static RP is
configured.
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 must 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 configuring 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

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
When the embedded RP feature is 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. Thus, the DR does not need to know the RP
address beforehand.
The default embedded RP address scopes are FF7x::/12 and FFFx::/12. Here "x" refers to any legal
address scope. For more information about the Scope field, see "Multicast overview."
Perform this configuration on all routers in the IPv6 PIM-SM domain.
