Abstract— Route Redistribution involves the communication between different routing protocols. In this we discuss how the router
communicate with other routers using different types of routing protocols. A company having two branches with different routing
protocols and if two branches suddenly want to communicate with each other then we have to change the routing protocol of any one
of the branches which is very difficult. This problem can overcome by using redistribution
Keywords— RIP,EIGRP,OSPF,routing protocols,AD
I. INTRODUCTION
In general, protocols means set of rules. Routing protocols means set of rules used for routing purpose.
Redistribution allows us to communicate between the networks, which are using the different routing
protocols. Routing is the process of choosing a route for transferring the data packets across the networks.
All the packets forwarding in routing process is based on its routing table, which contains a note of all the
possible routes to various networks.
II. ROUTING PROTOCOLS
RIP:
RIP stands for routing information protocol, It works based on its hop count value. Hop count is
the way between the routers(i.e., if there are two neighbor routers, the route between those two neighbor
routers is referred as one hop). The maximum number of routers we can use in RIP routing protocol
network is only 16. RIP is a good choice for simple network. but, it is not preferred choice for large
networks. It is easy to configure RIP. In RIP, the routing updates for every 30sec. The AD value of RIP is
120.
EIGRP:
EIGRP stands for enhanced interior gateway routing protocol. It automatically update its routing
table. EIGRP uses BANDWIDTH, DELAY, LOAD, RELIABILITY and MTU as its metrics. EIGRP uses same
autonomous system number with in a network. The AD value of EIGRP is 5(for summary route).
OSPF:
OSPF stands for Open Shortest Path First, it is used to find the best possible route to reach the
destination. The AD value of OSPF is 110. OSPF routing protocol uses the area division concept. The
single autonomous system is divided into areas. Where each area contains a group of connected routers.
The main area is called area0 or backbone area. This routing protocol use cost as metric.

IV. CONCLUSIONS
In this we have analyzed the concert of the redistribution amongst three various routing protocols.
First we analyzed the rip, eigrp and ospf protocols individually. Then we executed redistribution among
the rip, eigrp and ospf routing protocols using CISCO PACKET TRACER software. In first scenario we
observed the redistribution between RIP and OSPF, in second scenario we observed the redistribution
between RIP and EIGRP,in third scenario we observed the redistribution between EIGRP and OSPF. By
observing these three scenarios, we can conclude how the information is distributed among different
routing protocols.
