metric than the standard static route. The Layer 3 switch always prefers the static route with the lower
metric. In this example, the Layer 3 switch always uses the standard static route for traffic to destination
network 192.168.7.0/24, unless that route becomes unavailable, in which case the Layer 3 switch sends
traffic to the null route instead.
FIGURE 5 Standard and null static routes to the same destination network
The next example shows another example of two static routes. In this example, a standard static route
and an interface-based static route are configured for destination network 192.168.6.0/24. The
interface-based static route has a lower metric than the standard static route. As a result, the Layer 3
switch always prefers the interface-based route when the route is available. However, if the interface-
based route becomes unavailable, the Layer 3 switch still forwards the traffic toward the destination
using an alternate route through gateway 192.168.8.11/24.
