6.5.3 Configuring the Timeout Period of a Neighbor

The timeout period of a neighbor can be set either globally or on an interface. If the multicast
device does not receive any Hello message from a neighbor when the timeout period is expired,
the device considers that the neighbor is unreachable. The timeout period of the neighbor must
be longer than the interval for sending Hello messages.
Context
Do as follows on the PIM-DM switch:
Procedure
l
l
Issue 01 (2011-10-26)
3. Run:
pim timer hello interval
The interval for sending Hello messages is set.
4. Run:
pim triggered-hello-delay interval
The maximum delay for triggering Hello messages is set.
After the maximum delay is set, the conflict caused by multiple PIM switchs sending
Hello messages simultaneously is prevented.
NOTE
The configuration involves the following two cases:
l Global configuration: It is valid on each interface.
l Configuration on an interface: The configuration on an interface takes precedence over the global
configuration. If the configuration on an interface is not done, the global configuration is used.
Global Configuration
1. Run:
system-view
The system view is displayed.
2. Run:
pim
The PIM view is displayed.
3. Run:
hello-option holdtime interval
The timeout period during which the neighbor is reachable is set.
If no Hello message is received from a neighbor in the timeout period, the neighbor
is considered unreachable.
Configuration on an Interface
