Configuring an alias for an interface

An Instant Internet unit can support multiple IP addresses and subnets on one
physical interface. Each IP address has a name that helps distinguish what each IP
address is being used for. The name that is given to each additional IP address is
its alias.
When combined with Static NAT, this is useful to publish additional public
addresses for Web and mail servers existing in the privately addressed local
network.

Example

The Eth1 interface may already have a private IP address and mask like
192.168.1.1/24. An alias interface could be added to Eth1 to provide an additional
address and mask, so that two different IP networks are operating on the same
physical interface. This is desirable in some cases where public and private
addresses are used on a single LAN, and an additional LAN segment is not
available (such as with an Instant Internet 100 unit).
without subnet information.
all known routers including information for subnet masks. (This version
is included in order to be backwards compatible for older versions of
Instant Internet. Use V2 Multicast for all other purposes).
messages to all known routers, including information for subnet masks,
but you minimize the load on other computers because the number of RIP
messages being sent and received are limited to computers with V2
Multicast enabled.
