Configuring An Rp - HP A8800 Configuration Manual

Step
3. Enable IPv6 BIDIR-PIM.

Configuring 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
means for the dynamic RP election mechanism to enhance the robustness and operation manageability
of a multicast network.
CAUTION:
When both IPv6 PIM-SM and IPv6 BIDIR-PIM run on the IPv6 PIM network, do not use the same RP to serve
IPv6 PIM-SM and IPv6 BIDIR-PIM. Otherwise, exceptions might occur to the IPv6 PIM routing table.
Configuring a static RP
If there is only one dynamic RP 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.
You must perform static RP configuration on all routers in the IPv6 PIM-SM domain and specify the same
RP address.
Perform this configuration on all routers in the IPv6 BIDIR-PIM domain.
To configure a static RP:
Step
1. Enter system view.
2. Enter IPv6 PIM view.
3. Configure a static RP for IPv6
BIDIR-PIM.
NOTE:
In IPv6 BIDIR-PIM, a static RP can be specified with a virtual IPv6 address. For example, if the IPv6
addresses of the interfaces at the two ends of a link are 1001::1/64 and 1001::2/64, you can specify a
virtual IPv6 address, like 1001::100/64, for the static RP. As a result, the link becomes an RPL.
Configuring a C-RP
In an IPv6 BIDIR-PIM 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, configure a legal C-RP address range and the range of multicast groups
to be served on the BSR. In addition, because every C-BSR has a chance to become the BSR, you must
configure the same filtering policy on all C-BSRs in the IPv6 BIDIR-PIM domain.
