this case), and is used by the receiver to verify which version of
RIP the packet was sent from.
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.
