VRRP Configuration Example

VRRP Configuration on Cisco

In this VRRP example, we will work on Cisco IOS and configure VRRP (Virtual Router Redundancy Protocol) on Cisco Routers.

Configuring VRRP is like configuring Cisco Proprietary protocol HSRP. There are only small command differences.

For our Cisco VRRP Example, we will use the below topology:


cisco-vrrp-example

Now, let’s configure VRRP on Cisco Routers and learn VRRP better.

IP Address Configuration

The first step is the IP address configuration on interfaces.

Switch A (config)# int fa0/1
Switch A (config-if)# no switchport
Switch A (config-if)# ip address 172.16.0.1 255.255.255.0
Switch A (config-if)# no shutdown
Switch B (config)# int fa0/1
Switch B (config-if)# no switchport
Switch B (config-if)# ip address 172.16.0.2 255.255.255.0
Switch B (config-if)# no shutdown

VRRP Process Creation with Virtual IP

VRRP process is created with the VRRP Group ID and the Virtual IP Address.Here, our VRRP Group ID is 1 and our Virtual IP address is 172.16.0.5.

Switch A (config-if)# vrrp 1 ip 172.16.0.5
Switch B (config-if)# vrrp 1 ip 172.16.0.5

VRRP Group Description

Like all descriptions, in VRRP, we can use description to give our VRRP group a memorable description.

Switch A (config-if)# vrrp 1 description Our-vrrp
Switch B (config-if)# vrrp 1 description Our-vrrp

VRRP Priority

For Master/Backup selection, VRRP priorities are configured. To manuplate VRRP selection and determine a Master manually, VRRP Priority values are important. The default one is 100 and the highest one is elected as VRRP Master.
