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 (ooding, 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 section 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 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 specied
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.
S3048–ON
Syntax
area area-id default-cost cost
To return default values, use the no area area-id default-cost command.
Parameters
area-id Specify the OSPF area in dotted decimal format (A.B.C.D.) or enter a number from zero
(0) to 65535.
cost Species the stub area’s advertised external route metric. The range is from zero (0) to
65535.
Defaults cost = 1; no areas are congured.
