Configuring static routes
19
Figure 200 shows an example of two static routes configured for the same destination network.
One of the routes is a standard static route and has a metric of 1. The other static route is a null
route and has a higher metric than the standard static route. The Brocade device always prefers
the static route with the lower metric. In this example, the Brocade device 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 Brocade device sends traffic to the null route instead.
FIGURE 200 Standard and null static routes to the same destination network
Figure 201 shows another example of two static routes. 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
Brocade device always prefers the interface-based route when the route is available. However, if
the interface-based route becomes unavailable, the Brocade device still forwards the traffic toward
the destination using an alternate route through gateway 192.168.8.11/24.
