Why did we move from OSPFv2 to OSPv3?
OSPF or The Open Shortest Path First is a network routing protocol used for routing traffic within an autonomous system. At a high-level, OSPF is designed to keep network topology information in each router within an autonomous system containing information about itself and its neighboring routers. By keeping this information, routers can determine the shortest path as data packets look to move from one router to another.
Now, one of the biggest reasons for the iteration from OSPFv2 to OSPFv3 was to accommodate IPv6. IPv6 is a 128-bit network device addressing scheme that was upgraded from its previous 64-bit addressing scheme with IPv4 to accommodate the increasing number of network-connected devices. In quite a fascinating way, research was pointing to 64-bit addressing running out of addresses to accommodate the growing interconnected device-dependant world. By moving to 128-bit addressing, IPv6 addressing supports 340 trillion trillion trillion devices. This astronomically large number provides enough addressing space to address every atom in the observable universe!
