Technical Summary The format of OSPF packets is not flexible enough to enable applications exchange arbitrary data, which may be necessary in certain situations. "OSPF Link-local Signaling" (LLS) describes a vendor specific, backward-compatible technique to perform link-local signaling, i.e., exchange arbitrary data on a link. "OSPF Restart Signaling" describes a mechanism using LLS that can be used as an alternative to that described in RFC 3623 for routers to signal that they've restarted. "OSPF Out-of-band LSDB resynchronization" describes a mechanism using LLS for routers to resynchronize their LSDB without causing topology changes, for example, when they have restarted and are using the above Restart signaling mechanism. Working Group Summary The LLS mechanism is being published as Experimental to document the original protocol; meanwhile, the OSPF Working Group is working on a standards-track version. The OSPF Working Group did not think that the Restart and Resynchronization items provided sufficient benefit over the existing work, later published as RFC 3623, to adopt them as work items. They are being published simply for information. Protocol Quality Bill Fenner reviewed these specifications for the IESG.
