Auto Detect Configuration Examples

Configuration Example for Auto Detect Implementation in Static Routing

Network requirements
z As shown in Figure 1-1, 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 1-1. The configuration procedure is
omitted.
z Configure Switch A.
# Enter system view.
<SwitchA> system-view
# Create detected group 8.
[SwitchA] detect-group 8
# Detect the reachability of 10.1.1.4/24, with 192.168.1.2/24 as the next hop, and the detecting number
set to 1.

[SwitchA-detect-group-8] quit
# Enable the static route when the detected group is reachable. The static route is invalid when the
detected group is unreachable.
