The topology above has two gateways that will run VRRP, R6 and R4. The host is on the LAN side, 10.30.1.0/24, and the Internet has a loopback of 220.127.116.11.
VRRP configuration is very straightforward and similar to HSRP. I entered the preempt command and it does not show up in a show run interface. That’s because it’s on by default.
Above shows the virtual MAC VRRP is using.
The authentication is the same as HSRP, but I created a new key chain for practice. This is the same for the tracking statement. If 18.104.22.168 on internet router goes down, the VRRP active member changes over.
Which shows on R4 when I shutdown the loopback interface.
