Control Parameters for Establishing the Neighbor Relationship
can be configured either globally or on an interface. The configuration
in the interface view is prior to the configuration in the PIM view.
When the interval is not configured in the interface view, the configuration
in the PIM view takes effect.
Prerequisites
Before configuring control parameters for establishing
the neighbor relationship, complete the following tasks:
Context
The configuration involves the following cases:
Global configuration: It is valid on all the interfaces.
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.
Procedure
- Global Configuration
- Access the system view.
system-view
- Access the PIM view.
pim [ vpn-instance vpn-instance-name ]
- Set the interval for sending Hello messages.
timer hello interval
- Set the timeout period of holding the reachable state
of a neighbor.
hello-option
holdtime interval
If no
Hello message is received after the interval expires, the neighbor
is considered unreachable.
- Configuration on an Interface
- Access the system view.
system-view
- Access the interface view.
interface interface-type interface-number
- Set the interval for sending Hello messages.
pim timer hello interval
- Set the maximum delay for triggering Hello messages.
pim triggered-hello-delay interval
This can prevent the conflict
of Hello messages sent by multiple PIM devices at the same time.
- Set the timeout period of holding the reachable state
of a neighbor.
pim hello-option
holdtime interval
If no
Hello message is received after the interval expires, the neighbor
is considered unreachable.
- Contain the Generation ID option in a received Hello
message.
pim require-genid
The
Hello message without the Generation ID option is rejected.
By default, the FW handles the Hello message without the Generation option.
