13 AUTO DETECT CONFIGURATION GUIDE
Auto Detect
Implementation in
Static Routing
You can bind a static route with a detected group. The auto detect function will
then detect the reachability of the static route through the path specified in the
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.
