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 document proposes extensions to OSPFv2 and

OSPFv3 for advertising optional router capabilities.  A new Router

Information (RI) Link State Advertisement (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

autonomous system (AS)).  [STANDARDS TRACK]
