An interface can have one primary IP address. To assign a primary IP address and a network mask to a network interface, use the following command, starting in global configuration mode.

Command

Purpose

Interface interface name

Enters the interface configuration mode.

 

 

ip address address l mask

Set a primary IP address for an interface.

 

 

5.1.1 Assign Multiple IP Addresses to Network Interfaces

The IC35516 software supports multiple IP addresses per interface. You can specify an unlimited number of secondary addresses. Secondary IP addresses can be used in a variety of applications:

There might not be enough host addresses for a particular network segment. Suppose your sub-netting allows up to 254 hosts per logical subnet, but you need to have 300 host addresses on one physical subnet. Using secondary IP addresses on the routers or access servers allows you to have two logical subnets using one physical subnet.

Many older networks were built using Level 2 bridges, and were not sub-netted. The use of secondary addresses can aid in the transition to a sub-netted, router-based network. Routers on an older, bridged segment can easily be made aware of multiple subnets are on that segment.

You can create a single network from subnets that are physically separated by another network by using a secondary address. In these instances, the first network is layered on top of the second network. Note that a subnet cannot appear on more than one active interface of the router at a time.

Note: If any router on a network segment uses a secondary address, all other routers on that same segment must also use a secondary address from the same network or subnet.
