ROUTING INFORMATION PROTOCOL (RIP)

ROUTING INFORMATION PROTOCOL (RIP)
This section is going to hit only the key areas of RIP, because that’s all that is really pertinent
to the BSCI exam. There are currently two versions of RIP in existence: RIP version 1 and RIP
version 2. Let’s take a brief look at the major differences between them.
RIP version 1 (RIPv1) is considered a classful routing protocol, whereas RIP version 2 (RIPv2) is
a classless routing protocol. The key difference between a classful and classless routing protocol
is that a classful routing protocol does not send a subnet mask in the update and a classless routing
protocol does. Classful versus classless routing is covered in more detail later in this chapter. Other
attributes RIPv2 has that RIPv1 doesn’t are as follows:
 Authentication of routing updates through the use of cleartext or MD5 (optional)
 Multicast route updates
 Next-hop addresses carried with each advertised route entry
In order to activate RIPv2 you must first enter the router rip command in
global configuration mode. After RIP has been activated on the router you
must enter the command version 2 in router configuration mode.
