Vrrp Configuration - Lenovo RackSwitch G8264CS Cli Command Reference

VRRP Configuration

© Copyright Lenovo 2017
Virtual Router Redundancy Protocol (VRRP) support on the G8264CS provides
redundancy between routers in a LAN. This is accomplished by configuring the
same virtual router IP address and ID number on each participating VRRP‐capable
routing device. One of the virtual routers is then elected as the master, based on a
number of priority criteria, and assumes control of the shared virtual router IP
address. If the master fails, one of the backup virtual routers will assume routing
authority and take control of the virtual router IP address.
By default, VRRP is disabled. Lenovo N/OS has extended VRRP to include virtual
servers as well, allowing for full active/active redundancy between switches. For
more information on VRRP, see the "High Availability" chapter in the Lenovo
RackSwitch G8264CS Application Guide for Lenovo Enterprise Network Operating
System 8.4.

interface <1‐126>
Configures VRRP authentication parameters for the IP interfaces used with the
virtual routers. To view command options, see page
Command mode: Router VRRP
