4 - Configuring the SAGEM F@st™ 1500 ADSL router

Parameter Description

General RIP Parameters

RIP mode Globally enables or disables RIP.

Auto summary If Auto summary is disabled, then RIP packets will include sub- network information from all subnetworks connected to the router. If enabled, this sub-network information will be summarized to one piece of information covering all subnetworks.

Table of current Interface RIP parameter

Interface The WAN interface to be configured.

Operation Mode

Disable: RIP disabled on this interface.

 

Enable: RIP enabled on this interface.

 

Silent: Listens for route broadcasts and updates its route table.

 

It does not participate in sending route broadcasts.

Version

Sets the RIP (Routing Information Protocol) version to use on

 

this interface.

Poison Reverse

A method for preventing loops that would cause endless

 

retransmission of data traffic.

 

 

Authentication

• None: No authentication.

Required

• Password: A password authentication key is included in the

 

packet. If this does not match what is expected, the packet will

 

be discarded. This method provides very little security as it is

 

possible to learn the authentication key by watching RIP

 

packets.

 

• MD5: An algorithm that is used to verify data integrity through

 

the creation of a 128-bit message digest from data input (which

 

may

 

be a message of any length) that is claimed to be as unique to

 

that specific data as a fingerprint is to a specific individual.

 

 

Authentication

Password or MD5 Authentication key.

Code

 

RIP sends routing-update messages at regular intervals and when the network topology changes. When a router receives a routing update that includes changes to an entry, it updates its routing table to reflect the new route. RIP routers maintain only the best route to a destination. After updating its routing table, the router immediately begins transmitting routing updates to inform other network routers of the change.
