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
device always prefers the interface-based route when the route is available. However, if the
interface-based route becomes unavailable, the device still forwards the traffic toward the
destination using an alternate route through gateway 192.168.8.11/24.

To configure a standard static IP route and a null route to the same network as shown in
on page 198, enter commands such as the following.
BigIron RX(config)# ip route 192.168.7.0/24 192.168.6.157/24 1
BigIron RX(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 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.

To configure a standard static route and an interface-based route to the same destination, enter
commands such as the following.
BigIron RX(config)# ip route 192.168.6.0/24 ethernet 1/1 1
BigIron RX(config)# ip route 192.168.6.0/24 192.168.8.11/24 3

Standard and interface routes to the same destination network
Two static routes to 192.168.7.0/24:
--Interface-based route through
port1/1, with metric 1.
--Standard static route through
gateway 192.168.8.11, with metric 3.
Router A
192.168.6.188/24
Port1/1
When route through interface
1/1 is available, Router A always
uses that route.
If route through interface
1/1 becomes unavailable,
Router A uses alternate
route through gateway
Router B
