5.5.4 Refusing to Receive the Hello Message Without the
Generation ID Option
When the Generation ID option in the Hello message received from an upstream neighbor
changes, it indicates that the status of the upstream neighbor changes. Therefore, you can
configure a PIM interface to deny the Hello messages without Generation ID options to obtain
the upstream neighbor status in real time.

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 [ vpn-instance vpn-instance-name ]
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
1. Run:
system-view
The system view is displayed.
2. Run:
interface interface-type interface-number
The interface view is displayed.
The interface can be a VLANIF interface, or an Loopback interface.
3. Run:
pim 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
