RIP Command Codes
The field VERSION contains the protocol version number (1 in this case), and is used by the receiver to verify which
version of RIP the packet was sent.
RIP 1 Message
RIP is not limited to TCP/IP. Its address format can support up to 14 octets (when using IP, the remaining 10 octets must
be zeros). Other network protocol suites can be specified in the Family of Source Network field (IP has a value of 2). This
will determine how the address field is interpreted.
RIP specifies that the IP address, 0.0.0.0, denotes a default route.
The distances, measured in router hops are entered in the Distance to Source Network, and Distance to Destination
Network fields.
RIP 1 Route Interpretation
RIP was designed to be used with classed address schemes, and does not include an explicit subnet mask. An extension to
version 1 does allow routers to exchange subnetted addresses, but only if the subnet mask used by the network is the same
as the subnet mask used by the address. This means the RIP version 1 cannot be used to propagate classless addresses.
Routers running RIP version 1 must send different update messages for each IP interface to which it is connected.
Interfaces that use the same subnet mask as the router's network can contain subnetted routes, other interfaces cannot. The
router will then advertise only a single route to the network.
RIP Version 2 Extensions
RIP version 2 includes an explicit subnet mask entry, so RIP version 2 can be used to propagate variable length subnet
addresses or CIDR classless addresses. RIP version 2 also adds an explicit next hop entry, which speeds convergence and
helps prevent the formation of routing loops.
RIP2 Message Format
The message format used with RIP2 is an extension of the RIP1 format:
RIP version 2 also adds a 16-bit route tag that is retained and sent with router updates. It can be used to identify the origin
of the route.
Because the version number in RIP2 occupies the same octet as in RIP1, both versions of the protocols can be used on a
given router simultaneously without interference.

RIP Global Configuration

To setup RIP for the IP interfaces configured on the Switch, the user must first globally enable RIP and then configure RIP
settings for the individual IP interfaces. To globally enable RIP on the Switch, open the Configuration folder to Layer 3
Networking and then open the RIP folder and click on the RIP Global Configuration link to access the following screen:
Figure 6- 115. RIP Global Settings window
To enable RIP, simply use the pull-down menu, select Enabled and click Apply.
