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.  The Router
Information (RI) Link State Advertisement (LSA) is defined for this
purpose.  In OSPFv2, the RI LSA will be implemented with an Opaque
LSA type ID.  In OSPFv3, the RI LSA will be implemented with a unique
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)).  This document obsoletes RFC 4970 by
providing a revised specification that includes support for
advertisement of multiple instances of the RI LSA and a TLV for
functional capabilities.

This document is a product of the Open Shortest Path First IGP Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
