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.
About RIP Routing Updates Introduction RIP defines a method for propagating routing information among routers. It provides IP software with the information needed to make intelligent routing decisions. The information, passed in RIP updates packets from router-to-router, consists of two items, a network ID and a hop count. A hop count is the number of routers through which a packet must pass on its way from a source to a destination network.
regarded R2 as an alternate path to Net 1. The second is called “poison reverse,” which stipulates that routes are advertised as unreachable on the interface on which the route is learned. Had poison reverse been used in the preceding example, R2 would have advertised Net 1 as unreachable in its RIP updates to R1. Again R1 would never have regarded R2 as an alternate path to Net 1.
Configuring Static Routes This section describes how to configure PortServer TS 8/16 for static routes. Related Information See the set route command in the Digi One/PortServer TS Command Reference.

Configuration Examples Chapter 17 This chapter provides several simple, but complete, configuration examples. If you find that the examples implement exactly the features needed for your network, simply copy them, making appropriate substitutions for site-specific information such as IP addresses.
Terminal Server Configuration Without RealPort In this configuration, PortServer TS 8/16 functions as a terminal server, providing Telnet and Rlogin access to hosts. This configuration enables the following: • Telnet or Rlogin access to the LAN-based hosts, both from locally-connected terminals and from devices accessing the LAN from the telephone network.
Terminal Server Configuration Using Autoconnection This example shows a PortServer TS 8/16 functioning as a terminal server implementing autoconnection. • The terminals are connected to autoconnect ports. Consequently, when a user presses a terminal key, an automatic connection to a host is made. • The modem ports are not configured for autoconnection, but a port user is, which means that as soon as this particular user supplies a login, an automatic connection to a host is made.
Terminal Server Configuration Using RealPort In this example, the PortServer TS 8/16 is simply providing ports for the LAN-based host using RealPort. The configuration is exceedingly simple because port attributes are configured on the host itself.
