ospf is routing protocol (protocol fill routing tabel of router with all possible routes in same AS)
ospf is link state routing protocol : (router hold the topologe of network - map of it- and if topology chang_state of one of his links(neighbour) _ ,it send lsa to all routers to draw the map again)

it start with :
router discover his neighbours with hello messages
send topology info (what is his RID

WAT IS COPNNECTED ROUTERS AND subnets
draw a map of network in topology database
run stf algorithm on that map to find the shortest route to each subnet
maintain his states (state of his neighbour routers and connected subnets ) with hello messages
if one of his states go down he send lsa to all routers tell them wat happen
then all routersw draw the map again,run stp algorithm
