OSPF version 3 (IPv6)
Table 219 lists the individual Brocade FastIron switches and the Open Shortest Path First (OSPF)
version 3 (IPv6) features they 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:
• The differences between OSPF Version 2 (OSPF V2) and OSPF Version 3 (OSPF V3).
• The link state advertisement types for OSPF Version 3.
