SMC Networks SMC7404BRA EU manual 4-32, Authentication Required

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.
