Step
2. Enter public network PIM view
or VPN instance PIM view.
3. Configure an interface to be a
C-RP for PIM-SM.
4. Configure a legal C-RP
address range and the range
of multicast groups to be
served.
Enabling auto-RP
Auto-RP announcement and discovery messages are respectively addressed to the multicast group
addresses 224.0.1.39 and 224.0.1.40. With auto-RP enabled on a device, the device can receive these
two types of messages and record the RP information carried in such messages.
To enable auto-RP:
Step
1. Enter system view.
2. Enter public network PIM view
or VPN instance PIM view.
3. Enable auto-RP.
Configuring C-RP timers globally
To enable the BSR to distribute the RP-set information within the PIM-SM domain, C-RPs must periodically
send C-RP-Adv messages to the BSR. The BSR learns the RP-set information from the received messages,
and encapsulates its own IP address together with the RP-set information in its bootstrap messages. The
BSR then floods the bootstrap messages to all PIM routers in the network.
Each C-RP encapsulates a timeout value in its C-RP-Adv message. Upon receiving this message, the BSR
obtains this timeout value and starts a C-RP timeout timer. If the BSR fails to hear a subsequent C-RP-Adv
message from the C-RP when the timer times out, the BSR assumes the C-RP to have expired or become
unreachable.
The C-RP timers need to be configured on C-RP routers.
To configure C-RP timers globally:
Step
1. Enter system view.
2. Enter public network PIM view
or VPN instance PIM view.
3. Configure the C-RP-Adv
interval.
