Figure 18. Symmetrical VRRP Configuration
In this configuration, half the hosts use 10.0.0.1/16 as their default route, and half use
10.0.0.2/16. IP address 10.0.0.1/16 is associated with virtual router
VRID=1 , and IP address
10.0.0.2/16 is associated with virtual router VRID=2 .
If Router R1, the Master for virtual router VRID=1 , goes down, Router R2 would take over
the IP address 10.0.0.1/16. Similarly, if Router R2, the Master for virtual router VRID=2 ,
goes down, Router R1 would take over the IP address 10.0.0.2/16.
Configuration of Router R1
The following is the configuration file for Router R1 in Figure 18 .
Router R1 is the owner of IP address 10.0.0.1/16. Line 4 associates this IP address with
virtual router
VRID=1 , so Router R1 is the Master for virtual router VRID=1 .
