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

                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

                the IESG as a Proposed Standard.

                an Informational RFC

                preference over other OSPF control traffic. 

   Done         Update OSPFv2 MIB and submit to IESG as a Standard, replacing 
                RFC 1850
