Auto Detect Configuration Examples
Configuration Example for Auto Detect Implementation in Static Routing
Network requirements
z
As shown in Figure 12-1 , create detected group 8 on Switch A; detect the reachability of the IP
address 10.1.1.4, with 192.168.1.2 as the next hop, and the detecting number set to 1.
z
On switch A, configure a static route to Switch C.
z
Enable the static route when the detected group 8 is reachable.
z
To ensure normal operating of the auto detect function, configure a static route to Switch A on
Switch C.

Configuration procedure
Configure the IP addresses of all the interfaces as shown in Figure 12-1 . The configuration procedure is
omitted.
z
Configure Switch A.
# Enter system view.
