Rip Version 1 Message Format; Rip 1 Message - D-Link DGS-3324SRi User Manual

D-Link DGS-3324SRi Intelligent Stackable Gigabit Ethernet Switch
A router can 'poison reverse' a route by adding an infinite (16) hop count to a route's advertisement. This is
usually used in conjunction with triggered updates, which force a router to send an immediate broadcast when an
update of an unreachable network is received.

RIP Version 1 Message Format

There are two types of RIP messages: routing information messages and information requests. Both types use
the same format.
The COMMAND field specifies an operation according the following table:
Command
1
2
3
4
5
9
10
11
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.
