Configuring Dynamic Routes Using Rip - Digi PortServer TS 8 Configuration And Administration Manual

Configuring Dynamic Routes Using RIP

This section describes how to configure PortServer TS 8/16 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 PortServer TS 8/16 is attached, no routing-specific
configuration is required.
• To enable routing over PPP, links be sure to use the netrouting field on the set user command
to configure how PortServer TS 8/16 handles RIP updates. You can configure the link so that
PortServer TS 8/16 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 PortServer TS 8/16 for dynamic routing with a set forwarding command that spec-
ifies state=active.
You may also want to turn on the poisonreverse and splithorizon fields to prevent the RIP slow
convergence problem discussed on page 9-3. See the discussion on the set forwarding command
provided in the Digi One/PortServer TS Command Reference for more information.
Example: Dynamic Routes
In this example, which shows only those commands and command fields pertinent to routing,
PortServer TS 8/16 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.
set forwarding state=active poisonreverse=on splithorizon=on
set user name=link1...netrouting=off
