Basic IP routing configuration task list

Displaying IP route information (see 

Rather than dynamically selecting the best route to a destination, you can configure one or more static routes 
to that destination. Once configured, a static route stays in the routing table indefinitely. When multiple static 
routes are configured for a single destination and the outbound interface of the current static route goes down, 
a backup route is activated, thus improving network reliability. Each route is assigned a default precedence 
value and cost value. Modifying these values allow you to set a preference for one route over the next. If static 
routes are redistributed through dynamic routing protocol to neighboring devices, only the active static route 
to a destination is advertised.

This procedure describes how to configure one or more static IP routes to the same destination

Mode: Administrator execution

Where the syntax is:

•

network—The IP address of the target network or subnet.

•

mask—A network mask where the 1 bits indicate the network or subnet, and the 0 bits indicate the host 
portion of the network address provided.

•

address—The IP address of a next-hop router that can access the target network or subnet.

•

interface—The name of the outgoing interface to use for the target network or subnet.

•

metric—This is an optional parameter. Specifies the desirability of the route when compared against other 
routes. The range is 0 through 15, where 0 is the preferred route. If no metric is specified, the static route is 
assumed to have a metric of 0.

To configure a default static IP route, use 0.0.0.0 for the network number 
and mask. A valid next-hop address or interface is required.

Example: Adding a static IP route 

In the following example, packets for network 20.0.0.0/24 will be routed to the device at 172.17.100.2. The 
Ethernet port 0 1 has the address 172.17.100.1/24 and is bound to the interface wan.

node>enable
node#configure
node(cfg)#context ip router
node(ctx-ip)[router]#route 20.0.0.0 255.255.255.0 172.17.100.2

The route is added to the routing database with the default metric 0. The router will forward packets to the 
20.0.0.0 network via the interface wan to the router on 172.17.100.2.
