Parameters
Interval: Specifies the interval at which RSVP sends hello requests, in the range of 1 to 60, in 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 function
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
