RIP
Overview
The Routing Information Protocol (RIP) is a routing protocol used with almost every TCP/IP 
implementation. Its function is to pass routing information from a router or gateway to a neighboring 
router(s) or gateway(s). RIP messages contain information about destinations which can be reached 
and the number of hops which are required. The hop-count is the basic metric of RIP and so RIP is 
referred to as a “distance vector protocol”. RIP messages are carried in UDP datagrams.
Functionality
You can configure RIP to selectively advertise networks remotely connected via a SLIP/PPP link on 
the Ethernet connection, and pass RIP routing information to remotely connected clients. As this can 
be undesirable in some environments, this behavior can be configured and is defaulted to the non-
routing behavior.
Transmission and reception of Routing Information Protocol (RIP) packets over PPP and SLIP 
connections can be configured on a per user basis or on a per serial port basis. 
The 
Routing
 parameter can be configured:
z
On the 
Advanced
 tab for Remote Access (PPP) and Remote Access (SLIP) profiles configured 
for a serial port to determine the exchange of RIP packets between the IOLAN and remotely 
connected users connected from the serial side. 
z
On the 
Services
 tab for each local user to determine the exchange of RIP packets between the 
IOLAN and remotely connected users connected from the serial side. 
z
By the RADIUS server for users authenticated by RADIUS, the RADIUS-defined 
Framed-
Routing
 parameter determines the exchange of RIP packets.
There are four options for setting the 
Routing
 parameters:
z
None—Routing information is not exchanged across the link. This is the default setting for a line 
and a locally defined user.
z
Send—Routing information is only transmitted to the remote user.
z
Listen—Routing information is only received from the remote user.
z
Send and Listen—Routing information is transmitted to and received from the remote user.
The local 
User Routing
 parameter or RADIUS 
Framed-Routing
 parameter, if set, override the serial 
port
 Routing
 parameter for a connection.
