Configuring an RP
An RP can provide services for multiple or all IPv6 multicast groups. However, only one RP at a time can
forward IPv6 multicast traffic for an IPv6 multicast group.
An RP can be manually configured or dynamically elected through the BSR mechanism. For a
large-scaled IPv6 PIM network, configuring static RPs is a tedious job. Generally, static RPs are backups
for dynamic RPs to enhance the robustness and operational manageability on an IPv6 multicast network.
Configuring a static RP
If only one dynamic RP exists on a network, you can configure a static RP to avoid communication
interruption caused by single-point failures. The static RP can also avoid waste of bandwidth due to
frequent message exchange between C-RPs and the BSR. The static RP configuration must be the same on
all routers in the IPv6 PIM-SM domain.
To configure a static RP:

2. Enter IPv6 PIM view.

3. Configure a static RP for IPv6
PIM-SM.
static-rp ipv6-rp-address
[ acl6-number | preferred ] *
By default, no static RP is
configured.
Configuring a C-RP
In an IPv6 PIM-SM domain, if you want a router to become the RP, you can configure the router as a C-RP.
HP recommends that you configure C-RPs on backbone routers.
The C-RPs periodically send advertisement messages to the BSR, which collects RP set information for the
RP election. You can configure the interval for sending the advertisement messages.
