Not configured by default.
z
For the configuration of Track-Static Routing collaboration, the specified static route can be an
existent or nonexistent one. For an existent static route, the static route and the specified Track
object are associated directly; for a nonexistent static route, the system creates the static route
and then associates it with the specified Track object.
z
The Track object to be associated with the static route can be a nonexistent one. After you use
the
track
command to create the Track object, the association takes effect.
z
If a static route needs route recursion, the associated Track object must monitor the next hop of
the recursive route instead of that of the static route; otherwise, a valid route may be considered
invalid.

Network requirements
As shown in
, Switch A, Switch B, Switch C, and Switch D 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.
Switch A 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 Switch A, with the next hop being Switch B and Switch C respectively. These two static routes
back up each other, where:
