Routing And Switching Questions
OSPFv2 and OSPFv3 are two versions of the Open Shortest Path First (OSPF) routing protocol. The main difference between OSPFv2 and OSPFv3 is the version of IP addressing they support.
OSPFv2 is designed to work with IPv4 addresses, which are the most commonly used addresses on the internet. It uses IPv4 addressing to establish and maintain routing tables, exchange routing information, and calculate the shortest path to a destination.
On the other hand, OSPFv3 is specifically designed to support IPv6 addresses, which are the next generation of IP addresses. It uses IPv6 addressing to perform the same functions as OSPFv2, but with the ability to handle the larger address space and additional features of IPv6.
In summary, OSPFv2 is used for IPv4 networks, while OSPFv3 is used for IPv6 networks.
