Preempt - Enterasys Matrix DFE-Gold Series Configuration Manual

preempt

Parameters
vlan vlan‐id
vrid
ip‐address
critical‐priority
Defaults
If not specified, critical‐priority will be set to 10.
Mode
Router command, Router configuration: Matrix>Router(config‐router)#
Usage
A critical IP address defines an interface — in addition to the interface between hosts and a first‐
hop router — that will prevent the master router from functioning properly if the interface were to
fail. For example, an IP address of an interface connecting a master router to a router configured
for internet access would be considered a critical IP address for VRRP routing. Up to four critical
IP addresses can be configured on the device.
The "no" form of this command clears the critical IP address.
Example
This example shows how to set IP address 182.127.62.3 as a critical IP address associated with
VLAN 1, VRID 1:
Matrix>Router(config)#router vrrp
Matrix>Router(config-router)#critical-ip vlan 1 1 182.127.62.3
