Chapter 1 Configuring IP Unicast Routing
Configuring Protocol-Independent Features
Configuring Static Unicast Routes
Static unicast routes are user-defined routes that cause packets moving between a source and a
destination to take a specified path. Static routes can be important if the router cannot build a route to a
particular destination and are useful for specifying a gateway of last resort to which all unroutable
packets are sent.
Starting with Cisco IOS Release 12.2(58)SE, switches running the LAN base image support 16
user-configured static routes on SVIs. Static routing configuration is supported on the LAN base image
only with the default SDM template and only on SVI interfaces. No routing protocols are supported.
Beginning in privileged EXEC mode, follow these steps to configure a static route:
Use the no ip route prefix mask {address | interface} global configuration command to remove a static
route.
The switch retains static routes until you remove them. However, you can override static routes with
dynamic routing information by assigning administrative distance values. Each dynamic routing
protocol has a default administrative distance, as listed in Table 1-16. If you want a static route to be
overridden by information from a dynamic routing protocol, set the administrative distance of the static
route higher than that of the dynamic protocol.
Static routes that point to an interface are advertised through RIP, IGRP, and other dynamic routing
protocols, whether or not static redistribute router configuration commands were specified for those
routing protocols. These static routes are advertised because static routes that point to an interface are
considered in the routing table to be connected and hence lose their static nature. However, if you define

Step 1
configure terminal Enter global configuration mode.
Step 2
ip route prefix mask {address | interface} [distance] Establish a static route.
Step 3

the configuration.
Step 5
