RIP count to infinity and OSPF
There is split-horizon, poison-reverse, hold-down, triggered update mechanisms to handle count to infinity problem in RIP. I am a bit confused about why so many mechanisms are used?when and in what practical scenarios is each applicable? Is there a single mechanism which takes care of count to infinity problem. For example RIP RFC says that triggered updates need to be used when there are more than 3 gateways in a routing loop. How does one know in advance which mechanism to use?
Also, I read some documentation which says that OSPF converges quickly as compared to RIP bcos it is link state based. What exactly does this mean? How is a OSPF routing update different from RIP update ?
Please clarify. Thanks
