Open Shortest Path First v3 (OSPF6)

Open Shortest Path First v3 (OSPF6) is defined by RFC 5340 and is similar to OSPF v2, but operates with IPv6 networks. This, it is a link-state routing protocol that automatically locates neighboring IPv6 routers within an autonomous system, typically with multicast, and exchanges IPv6 routing information for networks each neighbor.

OSPF6 is an interior routing protocol (IGP), and facilitates routing between private links or segments of local networks.
