OSPF version 3 (IPv6)

Table 42 lists the Open Shortest Path First (OSPF) version 3 (IPv6) features Brocade ICX 6650

devices support. These features are supported with premium IPv6 devices running the full Layer 3

software image.

OSPF (IPv6) overview

Open Shortest Path First (OSPF) is a link-state routing protocol. OSPF uses link-state

advertisements (LSAs) to update neighboring routers about its interfaces and information on those

interfaces. The switch floods LSAs to all neighboring routers to update them about the interfaces.

Each router maintains an identical database that describes its area topology to help a router

determine the shortest path between it and any neighboring router:
