The output shows that when there is a fault on the link between AC 1 and AC 3, the priority of AC
1 decreases to 80. AC 1 becomes the backup, and AC 2 becomes the master. Packets from Client
to Host are forwarded through AC 2.

Network requirements
As shown in Figure 19 , AC 1, AC 2, AC 3, and AC 4 are connected to two segments 20.1.1.0/24 and
30.1.1.0/24. Configure static routes on these switches so that the two segments can communicate with
each other, and configure route backup to improve reliability of the network.
AC 1 is the default gateway of the hosts in segment 20.1.1.0/24. Two static routes to 30.1.1.0/24 exist on
AC 1, with the next hop being AC 2 and AC 3 respectively. These two static routes back up each other,
where:
• The static route with AC 2 as the next hop has a higher priority, and is the master route. If this route
is available, AC 1 forwards packets to 30.1.1.0/24 through AC 2.
• The static route with AC 3 as the next hop acts as the backup route.
• Configure static routing-track-NQA collaboration to determine whether the master route is available
in real time. If the master route is unavailable, the backup route takes effect, and AC 1 forwards
packets to 30.1.1.0/24 through AC 3.
Similarly, AC 4 is the default gateway of the hosts in segment 30.1.1.0/24. Two static routes to
20.1.1.0/24 exist on AC 4, with the next hop being AC 2 and AC 3 respectively. These two static routes
back up each other, where:
• The static route with AC 2 as the next hop has a higher priority, and is the master route. If this route
is available, AC 4 forwards packets to 20.1.1.0/24 through AC 2.
• The static route with AC 3 as the next hop acts as the backup route.
• Configure static routing-track-NQA collaboration to determine whether the master route is available
in real time. If the master route is unavailable, the backup route takes effect, and AC 4 forwards
packets to 20.1.1.0/24 through AC 3.
