989BConfiguring an RP
An RP can be manually configured or dynamically elected through the BSR mechanism. For a large IPv6
PIM network, static RP configuration is a tedious job. Generally, static RP configuration is just a backup
method for the dynamic RP election mechanism to enhance the robustness and operation manageability
of a multicast network.
1791BConfiguring a static RP
If only one dynamic RP exists in a network, manually configuring a static RP can avoid communication
interruption because of single-point failures. It can also avoid frequent message exchange between C-RPs
and the BSR.
To make 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.
To configure a static RP:

Command Remarks
1411. Enter system view. system-view N/A
1412. Enter IPv6 PIM view.
pim ipv6 N/A
1413. Configure a static RP for
IPv6 PIM-SM.
static-rp ipv6-rp-address
[ acl6-number ] [ preferred ]
By default, no static RP is
configured.
1792BConfiguring 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.
