Junos VRRP with Tracking


Virtual Router Redundancy Protocol (VRRP) is commonly deployed on corporate networks in order to maintain default gateway redundancy for hosts. In this post, I will show you the commands to configure VRRP with route-tracking and interface-tracking.

For this lab, I will be using EVE-NG with four vSRX running 12.1X47-D15.4 code in packet-mode. I am using this version as it has the same features as newer codes, yet is less impactful on my lab hardware. The diagram for this lab is below, you can find the starting and ending configs at my GitHub repository. The root password for the devices is juniper123. BGP has been configured between INET and WAN1/WAN2 and is passing a default (0/0) route.

First up we will configure our VRRP on WAN1 and WAN2 using the virtual IP of To configure VRRP there are a few things we need to remember in Junos.

  • The VRRP group on both routers has to match
  • In order to ping, you need to configure accept-data
  • VRRP is configured under the interface IP address
  • Higher priority is the preferred master
  • Preempt is required if you want to allow for the backup to take over
