OSPFv3 is a link-state routing protocol for IPv4 and IPv6. the state of a link is, called the LSA, is a description of an interface and how it is connected to other routers, it includes the IPv6 prefix, network mask, network type and some other details. Each OSPF router uses LSAs to build the LSDB (Link State Database). The dijkstra algorithm is run for each entry in the LSDB, which results in having the shortest path to each destination in the routing table.
