Configuring static routes

FIGURE 201 Standard and interface routes to the same destination network
To configure a standard static IP route and a null route to the same network as shown in Figure 200
on page 793, enter commands such as the following.
Brocade(config)# ip route 192.168.7.0/24 192.168.6.157/24 1
Brocade(config)# ip route 192.168.7.0/24 null0 3
The first command configures a standard static route, which includes specification of the next-hop
gateway. The command also gives the standard static route a metric of 1, which causes the
Brocade device to always prefer this route when the route is available.
The second command configures another static route for the same destination network, but the
second route is a null route. The metric for the null route is 3, which is higher than the metric for the
standard static route. If the standard static route is unavailable, the software uses the null route.
For complete syntax information, refer to “Configuring a static IP route” on page 786.
To configure a standard static route and an interface-based route to the same destination, enter
commands such as the following.
Brocade(config)# ip route 192.168.6.0/24 ethernet 1/1 1
Brocade(config)# ip route 192.168.6.0/24 192.168.8.11/24 3
The first command configured an interface-based static route through Ethernet port 1/1. The
command assigns a metric of 1 to this route, causing the Brocade device to always prefer this route
when it is available. If the route becomes unavailable, the Brocade device uses an alternate route
through the next-hop gateway 192.168.8.11/24.
