Authentication

Required

Authentication

Code

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: An algorithm that is used to verify data integrity through the creation of a 128-bitmessage 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.

Password or MD5 Authentication key.

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

	S = Static Modem-Router
	R = RIP (Routing Information Protocol) assigned
	route.
	I = ICMP (Internet Control Message Protocol)
	Redirect route.
Network	Destination IP address
Address
Netmask	The subnetwork associated with the destination.
	This is a template that identifies the address bits
	in the destination address used for routing to
	specific subnets. Each bit that corresponds to a
	“1” is part of the subnet mask number; each bit
	that corresponds to “0” is part of the host number.
Gateway	The IP address of the Modem-Router at the next
	hop to which frames are forwarded.
Interface	The local interface through which the next hop of
	this route is reached.
Metric	When a Modem-Router receives a routing update
	that contains a new or changed destination
	network entry, the Modem-Router adds 1 to the
	metric value indicated in the update and enters
	the network in the routing table.
