Introduction to Routing

Introduction to Routing

This section provides some introductory information on routing.

What is Routing

Routing is the method, employed by IP software, of choosing a path over which to send packets 
between systems on different physical networks. When PortServer TS 8/16 is configured as a router, 
it performs this service.

Types of Routing

PortServer TS 8/16 can be configured to perform the following types of routing:

Static routing. When you use static routing, you manually configure routes to other networks for 
PortServer TS 8/16. Static routing works fine for small, stable networks. Maintaining static 
routes is difficult on larger networks and on networks that experience a lot of changes.

Dynamic routing. When you use dynamic routing, routes are not manually configured but are 
automatically established and maintained using information provided by routing information 
protocol (RIP). Route maintenance is obviously easier using RIP, but RIP has some shortcom-
ings that are discussed later in this chapter. PortServer TS 8/16 supports the RIP 1 standard. 

Proxy ARP, which is a technique in which a router answers ARP requests intended for another 
system. Typically, you use proxy ARP to move packets between physical networks that use the 
same IP network address. By pretending to be the other system, the PortServer TS 8/16 accepts 
responsibility for forwarding packets to that system. Proxy ARP makes routing decisions based 
on either static routes or on routing information provided by RIP.
