Sample Configurations
VRRP for IPv4 Configuration
The configuration in
comprehensive directions and is intended to provide guidance for only a typical VRRP configuration. You
can copy and paste from the example to your CLI. Be sure you make the necessary changes to support your
own IP addresses, interfaces, names, etc.

State Master: R2 was the first
interface configured with VRRP
Virtual MAC is automatically
assigned and is the same on
both Routers
State Backup: R3 was the second
interface configured with VRRP
