Open Shortest Path First (OSPFv2 and OSPFv3)

Open Shortest Path First version 2 for IPv4 is supported on platform.

OSPF is an Interior Gateway Protocol (IGP), which means that it distributes routing information between routers in a single Autonomous System (AS). OSPF is also a link-state protocol in which all routers contain forwarding tables derived from information about their links to their neighbors.

The fundamental mechanisms of OSPF (flooding, DR election, area support, SPF calculations, and so on) are the same for OSPFv2 and OSPFv3. OSPFv3 runs on a per-link basis instead of on a per-IP-subnet basis.

This chapter is divided into two sections. There is no overlap between the two sets of commands. You cannot use an OSPFv2 command in the IPv6 OSPFv3 mode.

NOTE: Dell Networking Operating System (OS) version 7.8.1.0 introduces Multi-Process OSPF on IPv4 (OSPFv2) only. It is not supported on OSPFv3 (IPv6).

The CLI requires that you include the Process ID when entering ROUTER-OSPF mode. Each command entered applies to the specified OSPFv2 process only.

OSPFv2 Commands

The Dell Networking implementation of OSPFv2 is based on IETF RFC 2328. .

area default-cost
