Technical Summary
 
   It is useful for routers in an OSPFv2 or OSPFv3 routing domain to
   know the capabilities of their neighbors and other routers in the
   routing domain.  This draft proposes extensions to OSPFv2 and OSPFv3
   for advertising optional router capabilities.  A new Router
   Information (RI) LSA is proposed for this purpose.  In OSPFv2, the RI
   LSA will be implemented with a new opaque LSA type ID.  In OSPFv3,
   the RI LSA will be implemented with a new LSA type function code.  In
   both protocols, the RI LSA can be advertised at any of the defined
   flooding scopes (link, area, or AS).
