CONFIGURING THE BARRICADE

Parameter

Description

Authentication Required

None: No authentication.

 

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: MD5 is 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 Code

Password or MD5 Authentication key.

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.
