Configuring Dynamic Routes Using RIP
This section describes how to configure Digi One/PortServer TS 2/4 for dynamic routing.
Related Information
See the set forwarding command in the Digi One/PortServer TS Command Reference.
Starting Point
This procedure assumes that you have sign on as root and have or will configure modems, modem scripts, devices, and filters for routes that use serial lines.
Procedure
1.Configure the links over which routed packets and RIP updates will be sent.
•To enable routing over the LAN to which Digi One/PortServer TS 2/4 is attached, no rout-
•To enable routing over PPP, links be sure to use the netrouting field on the set user command to configure how Digi One/PortServer TS 2/4 handles RIP updates. You can configure the link so that Digi One/PortServer TS 2/4 does any of the following with RIP updates:
—Both sends and receives them (netrouting=both)
—Sends them only (netrouting=send)
—Receives them only (netrouting=receive)
—Neither sends nor receives them (netrouting=off)
2.Configure the Digi One/PortServer TS 2/4 for dynamic routing with a set forwarding command that specifies state=active.
You may also want to turn on the poisonreverse and splithorizon fields to prevent the RIP slow convergence problem discussed on page
Example: Dynamic Routes
In this example, which shows only those commands and command fields pertinent to routing, Digi One/PortServer TS 2/4 is configured for dynamic routing using RIP. But to prevent RIP updates from being sent across the PPP link, the set user command that defines the link specifies netrouting=off.
