Usage Guidelines

Usage Scenario

If a node does not receive any Refresh message about PSB or RSB within a specified time period, the node deletes the state. You can run this command to modify the number of retry times for Refresh messages to change of the timeout period.

Prerequisites

RSVP-TE has been enabled by running the mpls rsvp-te command.

Precautions

The timeout period is calculated by using the following formula:

Timeout period = (keep-multiplier-number + 0.5) x 1.5 x refresh-interval.

In the formula, keep-multiplier-number specifies the number of retry times allowed for RSVP Refresh messages; refresh-interval specifies the interval at which RSVP Refresh messages are sent. To set these two parameters, run the mpls rsvp-te timer refresh command.

Example

# Set the number of retry times for RSVP Refresh messages to 5.
