11.3.6 Example for configuring link-state tracking
Networking requirements
As shown in Figure 11-6, to improve network reliability, Link 1 and Link 2 of Switch B are
connected to Switch A and Switch C respectively. Link 1 is the active link and Link 2 is the
standby link. Link 2 will not be used to forward data until Link 1 is faulty.
Switch A and Switch C are connected to the uplink network in link aggregation mode. When
all uplink interfaces on Switch A and Switch C fails, Switch B needs to sense the fault in time
and switches traffic to the standby link. Therefore, you should deploy link-state tracking on
Switch A and Switch C.

Configuration steps
Step 1 Configure link-state tracking on Switch A.
Create a LAG. Add uplink interfaces GE 1/1/1 and GE 1/1/2 to the LAG.
