Configuring An Rp - HP 6125XLG Ip Multicast Configuration Manual

IMPORTANT:
All the interfaces on the same router must operate in the same PIM mode in the public network or the same
VPN instance.
To enable PIM-SM:
Step
1. Enter system view.
2. Enable IP multicast routing
and enter MRIB view.
3. Return to system view.
4. Enter interface view.
5. Enable PIM-SM.

Configuring an RP

An RP can provide services for multiple or all multicast groups. However, only one RP can forward
multicast traffic for a multicast group at a time.
An RP can be manually configured or dynamically elected through the BSR mechanism. For a
large-scaled 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 a 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 also prevents frequent message exchange
between C-RPs and the BSR.
The static RP configuration must be the same on all routers in the PIM-SM domain.
To configure a static RP:
Step
1. Enter system view.
2. Enter PIM view.
Configure a static RP for

PIM-SM.
Configuring a C-RP
IMPORTANT:
When you configure a C-RP, reserve a relatively large bandwidth between the C-RP and other devices in
the PIM-SM domain.
In a 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.
