This chapter describes IP Routing services based upon the Routing Information
Protocol (RIP—both RIP-1 and RIP-2 are supported), and using static routes im-
plemented in the Intel Express 8100 Router.
In an IP environment, any station connected to an IP network is referred to as a
host. IP Routing is based upon RIP (Routing Information Protocol). When IP
packets are routed, they are routed from a source host to a destination network
without knowing if the destination address exists on the destination network.
It is assumed that you are familiar with the terminology and the protocols used in
IP environments.
See the Preface for a list of Requests for Comments (RFCs) concerning IP rout-
ing.
An IP address consists of a network part and a host part. The network part of the
IP address must be globally unique and are assigned by InterNIC (International
Network Information Center). However, addresses are often provided by the net-
work provider. For more information about the InterNIC project consult the RFC
1594.
The host part of an IP address is the responsibility of the network manager.
In private networks, where connections to other IP networks are not desired, lo-
cally assigned network addresses can be used.
In the current IP Routing implementation in the Intel Express 8100 Routers the
only broadcast packets forwarded are BootP broadcasts.
