Open Shortest Path First (OSPFv2 and OSPFv3)
Overview
Open Shortest Path First version 2 for IPv4
Open Shortest Path First version 3 (OSPFv3) for IPv6
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, etc.) 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 2 sections. There is no overlap between the two sets of commands. You
cannot use an OSPFv2 command in the IPv6 OSPFv3 mode.

OSPFv2 Commands
The Dell Force10 implementation of OSPFv2 is based on IETF RFC 2328. The following commands
enable you to configure and enable OSPFv2.

The C-Series supports OSPFv3 with FTOS version 7.8.1.0 and later.
OSPFv2 Commands
OSPFv3 Commands
Note:
FTOS version 7.8.1.0 introduces Multi-Process OSPF on IPv4 (OSPFv2) only. It is not
supported on OSPFv3 (IPv6).
Note that the CLI now requires that the Process ID be included when entering the ROUTER-OSPF
mode. Each command entered applies to the specified OSPFv2 process only.
