Technical Summary
   This document describes an extension to the OSPF protocol to
   reduce periodic flooding of Link State Advertisements in 
   stable topologies.  It generalizes the use of DoNotAge LSAs
   (originally used only in dial-on-demand configurations) to
   reduce or eliminate refreshing of unchanging topology information.
