Command Reference Guide
ip address <ipv4 address> <subnet mask>
Use the ip address command to define an Internet Protocol version 4 (IPv4) address on the specified
interface. Use the optional secondary keyword to define a secondary IPv4 address. Use the no form of this
command to remove a configured IPv4 address. Variations of this command include:
ip address <ipv4 address> <subnet mask>
ip address <ipv4 address> <subnet mask> secondary
Syntax Description
<ipv4 address>
<subnet mask>
secondary
Default Values
By default, there are no assigned IPv4 addresses.
Command History
Release 5.1
Release 9.1
Functional Notes
Use secondary IPv4 addresses to allow dual subnets on a single interface (when you need more IPv4
addresses than the primary subnet can provide). When using secondary IPv4 addresses, avoid routing
loops by verifying that all devices on the network segment are configured with secondary IPv4 addresses
on the secondary subnet.
Usage Examples
The following example configures an IPv4 address of 192.22.72.101 255.255.255.252:
(config)#interface tunnel 1
(config-tunnel 1)#ip address 192.22.72.101 255.255.255.252
60000CRG0-35E
Specifies a valid IPv4 address. IPv4 addresses should be expressed in
dotted decimal notation (for example, 10.10.10.1).
Specifies the subnet mask that corresponds to a range of IPv4 addresses
(network) or a specific host. Subnet masks can be expressed in dotted
decimal notation (for example, 255.255.255.0) or as a prefix length (for
example, /24).
Optional. Configures a secondary IPv4 address for the specified interface.
