OSPF Usage.

If I need to use OSPF as the only routing protocol in my network would that be fine , instead of mixing different routing protocols?
I know for internet BGP is the right protocol, but for LAN/WAN I think I can use OSPF and never worry about RIP2 or IS-IS or EIGRP.

is this correct? if so I don't need to worry about RIP2 and EIGRP and their configuration.

Sure, that actually simplifies things to only run one protocol.

so is there any reason why people learn different protocols.?

is there a situation where one protocol works better than the other?

Well, learning is completely different.  Most people want to learn all protocols as you will eventually run into all of them at one point in your career (if network focused).

Yes, some protocols work better in certain situations and others will only work in certain situations, i.e. EIGRP on Cisco equipment.  RIP is simple but doesn't scale but might work just fine in a small network.  EIGRP scales well and is simpler than OSPF.  OSPF is standard based and scales well but is more complex than EIGRP.  IS-IS scales really well but is not typically not found in enterprise networks.

through your description
it sounds already that OSPF can do it all.
IT's good for small and large network and different vendors. It's complexe , but if you know it you can configure your network without needing to know any other protocol
