hello interval

Use hello interval to set the interval for sending hello requests.

Use undo hello interval to restore the default.

Syntax

hello interval interval

undo hello interval

Default

Hello request messages are sent at an interval of 5 seconds.

Views

RSVP view

Predefined user roles

network-admin

Parameters

interval: Specifies the interval at which RSVP sends hello requests, in the range of 1 to 60 seconds.

Usage guidelines

If no hello request is received from a neighbor within the hello interval, the device sends a hello request to the neighbor. If the device receives a hello request from a neighbor within the interval, it immediately replies the neighbor with a hello ACK message.

The hello interval command takes effect only on interfaces that have the RSVP hello extension feature enabled (by using the rsvp hello enable command).

Examples

# Set the interval for sending hello request messages to 10 seconds.

<Sysname> system-view
[Sysname] rsvp
[Sysname-rsvp] hello interval 10
