Description of Working Group:

The OSPF Working develops and documents extensions and bug fixes to the
OSPF protocol, as well as documenting OSPF usage scenarios.
The specific protocol work items area listed in the Goals and
Milestones section below. Additional work items will require
rechartering.

Goals and Milestones:

Done  Gather operational experience with the OSPF protocol and submit the document as an Informational RFC.
Done  Develop multiple implementations, and test against each other.
Done  Design the routing protocol, and write its specification.
Done  Obtain performance data for the protocol.
Done  Make changes to the specification (if necessary) and publish the protocol as a Draft Standard RFC.
Done  Submit OSPF for IPv6 to IESG for consideration as a Standard.
Done  Update the OSPF NSSA option specified in RFC 1587 and submit to IESG for consideration as a Proposed Standard
Done  Develop Traffic Engineering extensions for OSPFv2 and submit it to the IESG as a Proposed Standard
Done  Submit to IESG a document which updates RFC 1793 allowing detection of demand circuit neighbors whose OSPF process has exited.
Done  Submit to IESG a BCP advocating that OSPF LSA refreshes be spread out over time
Done  Develop a hitless restart mechanism for OSPF and submit it to the IESG as a Proposed Standard.
Done  Document Alternative ABR implementations and submit ti IESG as an Informational RFC
Done  Extend the hitless restart mechanism to OSPFv3 and submit it to the IESG as a Proposed Standard
Done  Submit to IESG a BCP advocating that OSPF Hellos be given preference over other OSPF control traffic.
Done  Update OSPFv2 MIB and submit to IESG as a Standard, replacing RFC 1850
