Comparison between RIP, EIGRP, IGRP, and OSPF

what is difference between RIP, EIGRP, IGRP and OSPF?

Sr.No	RIP	EIGRP	IGRP	OSPF
1	RIP Stands For Routing Information protocol.	EIGRP Stands For Enhanced Interior Gateway Routing protocol.	IGRP Stands For Interior Gateway Routing protocol.	OSPF stands For Open shortest path First.
2	It Is a Industry standard dynamic routing protocol.	It Is a Cisco standard routing protocol.	It is a Cisco standard routing protocol.	It Is a Industry standard routing protocol.
3	It is not a more intelligent dynamic routing protocol.	It Is a more intelligent routing protocol than RIP and IGRP.	It is a more intelligent routing protocol than RIP	It is a more intelligent routing protocol than RIP, IGRP and EIGRP.
4	It is basically use for smaller size organization.	It is basically use for medium to lager size organization in the network.	It is basically use for medium to larger size organization in the network.	It is basically use for larger size organization in the network
5	It support maximum 15 routers in the network. 16 router is unreachable	It supports maximum 255 routers in the network.	It supports maximum 255 routers in the network.	It supports unlimited router in the network
6	RIP is denoted by R in routing table.	EIGRP is denoted by D in routing table.	It Is denoted by I in routing table	It Is denoted by O in routing table
7	It’s Administrative Distance Is 120.	It’s Administrative distance Is 90.	It’s Administrative Distance Is 100.	It’s Administrative distance is 110.
8	In RIP routing protocol we cannot create a separate administrative boundary in the network.	In EIGRP routing protocol we can create a separate administrative boundary in the   network with the help of autonomous system No.	In IGRP routing protocol we can create a separate administrative boundary in the network with the help of autonomous System No.	In OSPF routing protocol we can create a separate administrative boundary in the network through area no. within the same area all of the routers are exchanging the route information from neighbor router in the network.
9	It calculates the metric In terms of Hop Count from source network to destination network. Lower the Hop count that is the best route for that particular network.	It calculates the metric In terms of bandwidth and delay.	It calculates the metric in terms of bandwidth and delay. It Is also called composite metric.	It calculates the metric in terms of bandwidth.
10	RIP  works on Bellman Ford algorithm.	EIGRP works on DUAL(Diffusing Update Algorithm) Algorithm.	IGRP works On Bellman ford Algorithm.	OSPF works on DIJKSTRA Algorithm.
11	RIPv1 Do Not Support VLSM. RIPv2 support VLSM.	EIGRP Supports VLSM.	IGRP do Not Support VLSM.	OSPF Supports VLSM.
12	RIP routing protocol creates two table in the router:     Routing Table ,Topology Table.	EIGRP routing protocol creates three table In the router :  Neighbor Table, Topology Table,  Routing Table.	IGRP routing protocol creates three table In the router :   Neighbor Table ,  Topology Table,   Routing Table.	OSPF routing protocol creates three Table in the router:   Neighbor Table, Database Table ,  Routing Table.
