Routing Information Protocol (RIP)

Routing Information Protocol (RIP), as it is more commonly used than any other Routing
Protocols, for use in small, homogeneous networks. It is a classical distance-vector rout-
ing protocol with using hop count. RIP is formally defined in documents in Request For
Comments (RFC) 1058 and Internet Standard (STD) 56. As IP-based networks became
both more numerous and greater in size, it became apparent to the Internet Engineeing
Task Force (IETF) that RIP needed to be updated. Consequently, the IETF released RFC
1388, RFC 1723 and RFC 2453, which described RIP v2 (the second version of RIP).
RIP v2 uses broadcast User Datagram Protocol (UDP) data packets to exchange routing
information. The hiD 6615 S323 sends routing information and updates it every 30 sec-
onds. This process is termed advertised. If a router does not receive an update from an-
other router for 180 seconds or more, it marks the routes served by the non-updating
router as being unusable. If there is still no update after 120 seconds, the router removes
all routing table entries for the non-updating router.
The metric that RIP uses to rate the value of different routes is hop count. The hop count
is the number of routers that should be traversed through the network to reach the desti-
nation. A directly connected network has a metric of zero; an unreachable network has a
metric of 16. This short range of metrics makes RIP an unsuitable routing protocol for
large networks.
A router that is running RIP can receive a default network via an update from another
router that is running RIP, or the router can source (generate) the default network itself
with RIP. In both cases, the default network is advertised through RIP to other RIP
neighbors. RIP sends updates to the interfaces in the specified networks.
If an interface's network is not specified, it will not be advertised in any RIP update. The
hiD 6615 S323 supports RIP version 1 and 2.
Routing functionalities such as RIP, OSPF, BGP and PIM-SM are only available for hiD
6615 S323. (Unavailable for hiD 6615 S223)

Enabling RIP

To use RIP protocol, you should enable RIP.
Step 1
To open Router Configuration mode, use the following command on Global Configuration
mode.
Command
router rip
no router rip
Mode
Opens Router Configuration mode and operates RIP
routing protocol.
Global
Restores all configurations involved in RIP to the de-
fault.
