refresh-reduction

When the user enables either of the refresh reduction extensions on an interface, outgoing RSVP packets sent on that interface sets the refresh reduction capability bit in the common RSVP header to indicate that the device is capable of receiving and processing refresh reduction messages and related objects.

Syntax

refresh-reduction bundle-message [ bundle-send-delay milliseconds ] | summary-refresh

no refresh-reduction bundle-message [ bundle-send-delay milliseconds ] | summary-refresh

Command Default

The RSVP bundle messages on the interface are disabled, by default.

Parameters

bundle-message

bundle-send-delay milliseconds: Specifies the bundle send delay value in milliseconds. the range is 20-1000 milliseconds, with a default of 40 milliseconds.

summary-refresh: Activates the refresh-reduction summary refresh.

Modes

MPLS RSVP mode (config-router-mpls-rsvp).

MPLS interface RSVP mode (config-router-mpls-eth-x/x-rsvp).

Usage Guidelines

Summary refresh is a more effective tool for RSVP refresh message overhead reduction.

Use the no version of the command to disable RSVP bundle messages.

MPLS is supported on the Extreme 8820, SLX 9740, SLX 9640, and SLX 9540 devices only.

Examples

The following commands enable RSVP bundle messages on interface 0/13 with a bundle-send-delay of 20 milliseconds.

device# configure
device(config)# router mpls
device(config-router-mpls)# mpls-interface ethernet 0/13
device(config-router-mpls-eth-0/13)# rsvp
device(config-router-mpls-eth-0/13-rsvp)# refresh-reduction bundle-message bundle-send-delay 20
