Open Shortest Path First (OSPFv2 and

Open Shortest Path First version 2 for IPv4 is supported on S6000 Dell Networking Operating System

(OS) platform. Open Shortest Path First version 3 (OSPFv3) for IPv6 is supported on the 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

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.

OSPFv2 Commands

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

Set the metric for the summary default route the area border router (ABR) generates into the stub area.

Use this command on the border routers at the edge of a stub area.

area area-id default-cost cost

To return default values, use the no area area-id default-cost command.

Specify the OSPF area in dotted decimal format (A.B.C.D.) or

enter a number from zero (0) to 65535.

Specifies the stub area's advertised external route metric. The

range is from zero (0) to 65535.
