Quidway S9300 Terabit Routing Switch
Configuration Guide - Multicast
If an S9300 receives a Prune message from an upstream interface, the S9300 learns that other
downstream S9300s exist in the LAN. If the S9300 still needs to receive multicast data, the
S9300 must send a Join message to the upstream device within the override-interval.
The prune control parameters can be set globally or on an interface.

The global configuration is valid for each interface.
The configuration on an interface is valid only for the specified interface. The configuration
on an interface takes precedence over the global configuration. If the prune control
parameters are not set on the interface, the global configuration is used.
Setting the forwarding control parameters globally
1. Run:
system-view
The system view is displayed.
2. Run:
pim
The PIM view is displayed.
3. Run:
hello-option lan-delay interval
The delay for transmitting messages in the LAN is set.
By default, the delay in transmitting a Prune message is 500 milliseconds.
4. Run:
hello-option override-interval interval
The interval for overriding the prune operation is set.
By default, the interval for overriding the prune operation is 2500 milliseconds.
Setting the prune control parameters on an interface
1. Run:
system-view
The system view is displayed.
2. Run:
interface interface-type interface-number
The interface view is displayed.
On the S9300, VLANIF interfaces and loopback interfaces support PIM.
3. Run:
pim hello-option lan-delay interval
The delay for transmitting messages in the LAN is set.
By default, the delay for transmitting a prune message is 500 milliseconds.
4. Run:
pim hello-option override-interval interval
The interval for overriding the prune operation is set.
