Editing Open Shortest Path First (section)

=== High-level changes ===
* Except for virtual links, all neighbor  exchanges use IPv6 link-local addressing exclusively. The IPv6 protocol runs per link, rather than based on the [[subnet]]. 
* All IP prefix information has been removed from the link-state advertisements and from the ''hello'' discovery packet, making OSPFv3 essentially protocol-independent. 
*  Three separate flooding scopes for LSAs:
** Link-local scope: LSA is flooded only on the local link and no further.
** Area scope: LSA is flooded throughout a single OSPF area. 
** AS scope: LSA is flooded throughout the routing domain.
* Use of IPv6 link-local addresses, for neighbor discovery, auto-configuration.
* Authentication has been moved to the [[IPsec|IP Authentication Header]]
