AUTO DETECT CONFIGURATION GUIDE

Auto Detect

You can bind a static route with a detected group. The auto detect function will

detected group.

 

 

 

 

 

 

 

 

 

The static route is valid if the detected group is reachable.

 

 

 

The static route is invalid if the detected group is unreachable.

Requirements

Make sure there is a route between Switch A and Switch B, Switch B and Switch C, Switch A and Switch D, and Switch D and Switch C.

On Switch A, configure two static routes to Host C with different preferences. The one with higher preference (smaller value) is used as the master route, and the other as the backup route.

Normally, Switch A adopts the master route to send data to Host C through Switch B.

Create detected group 8 on Switch A; detect the reachability of IP address 10.1.1.4/24, with the next hop being 192.168.1.2, and the detecting number being 1.

If the detected group 8 is reachable, the master route is valid, and Switch A adopts the master route to send data to Host C through Switch B.

If the detected group is unreachable, the master route is invalid, and Switch A adopts the backup route to send data to Host C through Switch D.

Similarly, configure two static routes to Host A on Switch C. Normally, Switch C sends data to Host A through Switch B.
