Overview

VRRP allows multiple routers to provide active/passive redundancy for a routing IP address used by devices on a broadcast domain.

  • VRRP Master - actively responds to the virtual IP address
  • VRRP Backup - elected as the master if advertisements from the master are no longer detected and begins responding to the virtual IP address
  • Virtual Router Identifier (VRID) - configured to match between VRRP routers


Configuration Overview

1. Configure a VRRP group and specify a VRID on an interface (physical or VLAN) in L3 mode with an IP address assigned.
2. Configure a virtual IP address for the VRRP group.
3. Optional - Configure VRRP Priority.




Configuration


Router 1
Command Purpose
R1# configure Enter configuration mode.
R1(conf)# interface VLAN 10 Enter an interface (physical or VLAN).
R1(conf-if-vl-10)# ip address 10.10.10.2 /24
R1(conf-if-vl-10)# no shutdown
Set an IP address on the interface and enable for L3 mode.
R1(conf-if-vl-10)# vrrp-group 10 Set VRRP group ID (VRID).
R1(conf-if-vl-10-vrid-10)# virtual-address 10.10.10.1 Set Virtual IP address for the VRRP router.
R1(conf-if-vl-10-vrid-10)# priority 200 (Optional) Set priority for Master election. Default is 100. Higher number takes priority. Range 1-255.


Router 2
Command Purpose
R2# configure Enter configuration mode.
R2(conf)# interface VLAN 10 Enter an interface (physical or VLAN).
R2(conf-if-vl-10)# ip address 10.10.10.3 /24
R2(conf-if-vl-10)# no shutdown
Set an IP address on the interface and enable for L3 mode.
R2(conf-if-vl-10)# vrrp-group 10 Set VRRP group ID (VRID)
R2(conf-if-vl-10-vrid-10)# virtual-address 10.10.10.1 Set Virtual IP address for the VRRP router.
R2(conf-if-vl-10-vrid-10)# priority 150 (Optional) Set priority for Master election. Default is 100. Higher number takes priority. Range 1-255
