scale-timer vrrp-extended

Configures a scale time factor that increases the timing sensitivity across all configured and default Virtual Router Redundancy Protocol Extended (VRRP-E) timers.
Syntax
scale-timer vrrp-extended scale-factor
no scale-timer vrrp-extended scale-factor
Command Default

VRRP timers are not scaled.

Parameters
scale-factor
A number representing the scale of the division of a VRRP-E configured interval timer or the default interval timer. Valid values are in a range from 1 through 10. The default value is 1.
Modes

VRRP-E router configuration mode

Usage Guidelines

Configuring the VRRP-E scale timer is supported only in VRRP-E sessions. When a scaling value is configured, the existing timer values are divided by the scaling value. For example: a value of 10 divides the timers by a factor of 10, allowing the default dead interval to be set to 300 ms. Using timer scaling, VRRP-E subsecond convergence is possible if a master VRRP device fails.

The no form of the command restores the default.

Note: Increased timing sensitivity as a result of this configuration could cause protocol flapping during periods of network congestion.
Examples

The following example scales all VRRP-E timers by a factor of 10. 

device# configure terminal
device(config)# router vrrp-extended
device(config-vrrpe-router)# scale-timer vrrp-extended 10
