Why is OSPF better than RIP?

[RachelG]

Hi!

I wonder why OSPF is the better choice instead of using RIP nowadays? Which advantages does OSPF have? Is there any part that OSPF is missing that RIP use?

Thanks for your answer!

Hi

Interesting question. I'd say that OSPF is more efficient then RIP but not necessarily better.

 Let's say you have a small network with less fancy router. Then RIP is 'better' then OSPF. Of course if the network is huge, then, RIP would be a wrong  option.

 In terms of feature RIP is a hop count protocol whilst OSPF is a link-state protocol. Then, OSPF is smarter and well prepared to avoid loops. But this comes with a price. You need more data, more memory, CPU, etc.

"Which advantages does OSPF have?"
OSPF has a per interface metric, which may allow a better path selection than RIP's per hop count.
OSPF handles classless IP (RIPv1 cannot - RIPv2 can do classless, but not as integrated as OSPF).
OSPF can handle much, much larger networks than RIP. (For one example, OSPF isn't limited to 15 hop diameters.)
OSPF can converge much faster than RIP.
However, a noted by Flavio, the above often is more demand of the network device, especially if the network is small.
