IP Routing
Use the no version to delete the loopback interface.
See interface loopback
Use to set an IP address for an interface or a subinterface.
Specify the layer 2 encapsulation before you set the IP address.
Example
host1(config-subif)#ip address 192.0.2.50 255.255.255.0
Use the no version to remove the IP address or to disable IP processing on the
interface.
See ip address
Use to establish a static route and associate it with a configured RTR operation.
Use the verify rtr keywords to instruct the router to install the static route in the
routing table only if the next hop to the specified destination address is resolved
and if the specified RTR operation is currently reachable. When you use the
verify rtr keywords, you must also specify the number of the associated RTR
operation.
Optionally, you can include the last-resort keyword when you use the verify
rtr keywords to instruct the router to install the static route in the routing table
even if the specified RTR operation is currently unreachable, provided that no
other static route to the same network prefix is available.
Example
host1(config)#ip route 10.1.1.5 255.255.255.0 10.1.1.5 fastEthernet 1/0 verify
rtr 5 last-resort
Use the no version to remove a static route from the routing table.
See ip route
Use to configure an unnumbered IP interface.
This command enables IP processing on an interface without assigning an explicit
IP address to the interface.
You must specify an interface location, which is the identifier of another interface
on which the router has an assigned IP address. This interface cannot be another
unnumbered interface.
Example 1
host1(config-if)#ip unnumbered fastEthernet 3/0
