The following four features are the
most significant new features added to RIP v2:
- Authentication of the
transmitting RIP v2 node to other RIP v2 nodes
– RIP v2 added
support for the authentication of the node that is transmitting
response messages. Response messages are used to propagate routing
information throughout a network. Authenticating the originator of a
response message was intended to prevent routing tables from being
corrupted with illegitimate routes from a fraudulent source.
- Subnet Masks
– RIP v2 allocates
a 4-octet field to associate a subnet mask to a destination IP
address. When used in tandem, the IP address and its subnet mask
enable RIP v2 to specifically identify the type of destination to
which the route leads. This allows RIP v2 to route to specific subnets,
regardless of whether the subnet mask is fixed or of variable
length.
- Next Hop IP addresses
– The
inclusion of a Next Hop identification field helps make RIP v2 more
efficient than RIP v1 by preventing unnecessary hops. This feature is
particularly effective for network environments using multiple
routing protocols simultaneously. Some routes go undiscovered when
there are multiple or dissimilar routing protocols.
- Multicasting RIP v2 messages
– Multicasting is a technique for simultaneously advertising routing
information to multiple RIP or RIP v2 devices. Multicasting is
beneficial whenever multiple destinations must receive the identical
information. The conventional solution to this problem would be to
generate separate packets containing identical payloads specifically
addressed to each machine. Multicasting enables packets to be
simultaneously delivered to multiple machines. This reduces overall
network traffic and reduces the processing load of the source
machine.
