IP Routing
In this chapter
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.
IP Concept
Concept description
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.
Background
knowledge
It is assumed that you are familiar with the terminology and the protocols used in
IP environments.
References See the Preface for a list of Requests for Comments (RFCs) concerning IP rout-
ing.
Address assignment
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.
Private networks
In private networks, where connections to other IP networks are not desired, lo-
cally assigned network addresses can be used.
BootP broadcasts only
In the current IP Routing implementation in the Intel Express 8100 Routers the
only broadcast packets forwarded are BootP broadcasts.
