This feature allows the device to adjust to changes in network topology. The device does not
continue trying to use routes on unavailable paths but instead uses routes only when their paths
are available.

FIGURE 10
The following command configures a static route to 207.95.7.0, using 207.95.6.157 as the
next-hop gateway.
BigIron RX(config)# ip route 207.95.7.0/24 207.95.6.157
When you configure a static IP route, you specify the destination address for the route and the
next-hop gateway or device interface through which the device can reach the route. The device
adds the route to the IP route table. In this case, Router A knows that 207.95.6.157 is reachable
through port 1/2, and also assumes that local interfaces within that subnet are on the same port.
Router A deduces that IP interface 207.95.7.188 is also on port 1/2.
The software automatically removes a static IP route from the IP route table if the port used by that
route becomes unavailable. When the port becomes available again, the software automatically
re-adds the route to the IP route table.
Configuring a static IP route
To configure an IP static route with a destination address of 192.0.0.0 255.0.0.0 and a next-hop
router IP address of 195.1.1.1, enter the following.
BigIron RX(config)# ip route 192.0.0.0 255.0.0.0 195.1.1.1
To configure a default route, enter the following.
BigIron RX(config)# ip route 0.0.0.0 0.0.0.0
To configure a static IP route with an Ethernet port instead of a next-hop address, enter a command
such as the following.
BigIron RX(config)# ip route 192.128.2.69 255.255.255.0 ethernet 4/1
The command configures a static IP route for destination network 192.128.2.69/24. Since an
Ethernet port is specified instead of a gateway IP address as the next hop, the device always
forwards traffic for the 192.128.2.69/24 network to port 4/1.
