416 CHAPTER 28: CONFIGURING RIP
Defining a Neighboring
Route
r
RIP is a broadcast protocol. It exchanges routing information with
non-broadcasting networks in unicast mode.
Perform the following configurations in RIP view.
Table 471 Define a Neighboring Router
By default, no neighboring routers are defined.
Normally, this command is not recommended because the node on the other end
does not need to receive two identical packets at the same time. Also when a peer
sends messages, it is also subject to the restrictions of such commands as
rip
work
, rip output, rip input and network.
Specifying RIP Version RIP-2 has two sending modes, broadcasting and multicasting, with message
multicasting as the default mode. The multicast address in RIP-2 is 224.0.0.9. The
advantage of multicasting is that the host not running RIP in the network does not
receive RIP broadcast messages. In addition, message multicasting can also prevent
the host running RIP-1 from incorrectly receiving and processing the routes with
subnet mask in RIP-2.
When RIP-1 is running on the interface, the interface receives and transmits the
broadcast packets of RIP-1 and RIP-2 but does not receive RIP-2 multicast
messages. When RIP-2 is running on the interface, the interface can receive and
transmit RIP-1 and RIP-2 broadcast packets but cannot receive RIP-2 multicast
packets. When the interface runs in RIP-2 multicast mode, it receives and transmits
the RIP-2 multicast packets and does not receive the RIP-1 and RIP-2 broadcast
packets.
Perform the following configurations in interface view.
Table 472 Specify RIP Version
By default, the interface runs RIP-1.
Configuring Check Zero
Field of RIP Version 1
The check zero command is used by the router to validate the version of the RIP
Version 1 message. RFC 1058 stipulates that the ZERO FIELD in the RIP Version 1
header must be set to zero. If the
checkzero parameter is set and the router
receives a message with the zero field not 0, the router will discard the RIP
message because it is the wrong version.
