Setting the PIM neighbor 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 timer hello interval
The interval for sending Hello messages is set.
By default, Hello messages are sent every 30 seconds.
4. Run:
pim hello-option holdtime interval
The timeout interval of the reachable status of a neighbor is set. If not receiving any
Hello message in the period, the S9300 considers that the neighbor is unreachable.
By default, the timeout interval is 105 seconds.
5. Run:
pim triggered-hello-delay interval
The maximum delay for triggering Hello messages is set. This command helps to
prevent multiple S9300s from sending Hello messages at the same time.
By default, the maximum delay for triggering Hello messages is 5 seconds.
The global configuration is valid for each interface.
The configuration on an interface is valid only for the specific interface. The configuration
on an interface takes precedence over the global configuration. If the DR election control
parameters are not set on the interface, the global configuration is used.
Setting the parameters for controlling DR election globally
1. Run:
system-view
The system view is displayed.
2. Run:
