3.4.2 Using Auto Detect with VRRP

I. Network requirements
Configure dynamic routing on Routers A, B, C, and D, ensuring the routes
between Routers A, B, and C are reachable, and the routes between Routers A, D,
and C are reachable.
Router B and Router D form a VRRP standby group numbered 1, whose virtual IP
address is 192.168.0.100.
Normally, data from Router A passes through Router B to reach Router C.
When the link between Router B and Router C fails, Router D becomes the master
in standby group 1 automatically and the data from Router A passes through
Router D to reach Router C.
