Information About OSPFv3

OSPFv3 is an IETF link-state protocol (see
a special message, called a
neighbor routers. Once a neighbor is discovered, the two routers compare information in the Hello packet
to determine if the routers have compatible configurations. The neighbor routers attempt to establish
adjacency, which means that the routers synchronize their link-state databases to ensure that they have
identical OSPFv3 routing information. Adjacent routers share
include information about the operational state of each link, the cost of the link, and any other neighbor
information. The routers then flood these received LSAs out every OSPF-enabled interface so that all
OSPFv3 routers eventually have identical link-state databases. When all OSPFv3 routers have identical
link-state databases, the network is
then uses Dijkstra's Shortest Path First (SPF) algorithm to build its route table.
You can divide OSPFv3 networks into areas. Routers send most LSAs only within one area, which
reduces the CPU and memory requirements for an OSPF-enabled router.
