Configuring Dynamic Routes Using RIP
54
•
The metric field indicates that packets to this subnet will pass
through two routers
•
The gateway field indicates that all packets using this route are to be
forwarded to the device at IP address 191.21.21.2.
set route net=199.21.33.44 mask=255.255.255.255 metric=2
wannname=ppp1 gateway=199.21.21.2
This section describes how to configure the device server 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 signed 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 device server 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 device server handles
RIP updates. You can configure the link so that device server 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 device server for dynamic routing with a set forwarding
command that specifies state=active.
Example: Dynamic Routes
In this example, which shows only those commands and command fields
pertinent to routing, device server 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.
