Comparison of Routing Protocols

I Guess this should suffice for a fair understanding of the routing protocols mentioned.

 

TABLE 1	RIP v1	RIP v2	IGRP
Metric on which it is based	Hop Count	Hop Count	Bandwidth / Delay
Administrative Distance	120	120	100
Max Hop count	15	15	255
VLSM Support	NO	YES	NO
Uses Algorithm	Bellman-Ford	Bellman-Ford	Bellman-Ford
Content of Routing Updates	Full Table	Full Table	Full Table
Frequency of Routing Updates	30 seconds	30 seconds	90 seconds
Update Address	Broadcast	224.0.0.9	224.0.0.10
Protocol / Port	UDP 520	UDP 520	IP protocol 9
Convergence	Slow	Slow	Slow

 

TABLE 2	EIGRP	OSPF	BGP
Metric on which it is based	Bandwidth / Delay	Cost	Many (weight, path length, localpref, origin, age of the path, etc etc)
Administrative Distance	Internal – 90 External – 170	110	Internal – 200 External – 20
Max Hop count	224	-na-	-na-
VLSM Support	YES	YES	YES
Uses Algorithm	DUAL	Dijkstra	Best Path
Content of Routing Updates	Only Changes	Only Changes	Only Changes
Frequency of Routing Updates	Only when change occurs	Only when change occurs	Only when change occurs
Update Address	224.0.0.10	224.0.0.5	-na-
Protocol / Port	IP protocol 88	IP protocol 89	TCP 179
Convergence	Very Fast	Fast	Medium
