Configuring a static RP
If only one dynamic RP exists in a network, manually 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 the following configuration on all the routers in the IPv6 PIM-SM domain.
To configure a static RP:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter IPv6 PIM view. pim ipv6 N/A
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. H3C 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.
To configure a C-RP:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter IPv6 PIM view. pim ipv6 N/A
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 |
advertisement-interval
adv-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.
