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:
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.
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.
VRRP Group Description
Like all descriptions, in VRRP, we can use description to give our VRRP group a memorable description.
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.
It is not required to configure VRRP Priority for switch B, because it is the default value. Here, we write this command to show you only.
To configure VRRP authentication, we will use the below command on switches. Our password is CISCO.
As you can see, VRRP and HSRP configuration is very similar. Only HSRP “standby” word is leaving us. Instead, for VRRP, “vrrp” is coming.
The Preempt mechanims is enabled on VRRP by default. To disable it, we can use “no vrrp preempt” command.
To verify the VRRP configuration we can use “show vrrp” and “show vrrp brief all” VRRP verification commands.
To disable VRRP, we can use “no vrrp 1 enable” command.
