Other additional and optional tasks will be introduced in the following sections:

Assign Multiple IP Addresses to a Network Interface

Enable IP Processing on a Serial Interface

5.2.3 Assign Multiple IP Addresses to a Network Interface

Each interface can own multiple IP addresses, including one primary IP address and arbitrary amount of secondary IP

addresses. In the following cases you should configure secondary IP address:

There might not be enough host addresses for a particular network segment. For example, a logical subnet has up to 254

valid IP addresses, but in factual application maybe 300 hosts are required to connect in. In this case you can make two

logical subnets use a same physical subnet through configuring secondary IP address on your router or your access server.

Some early networks are based on Level2 bridge, but not be split into multiple subnets. Judicious use of secondary

address can rebuild a network like such into multiple subnets based on routing. Through secondary IP, a router on a

network can acquaint multiple subnets in the same network.

Two subnets of a single network might be separated physically by another network. Here you can make the network

addresses to be secondary IP addresses, so that you can connect two subnets in a logical network but divided away

physically. <![endif]>
