   Title:   BGP Next-next Hop Nodes

Abstract:

   BGP speakers learn their next hop addresse for NLRI in [RFC4271] in
   the NEXT_HOP field and in [RFC4760] in the "Network Address of Next
   Hop" field.  Under certain circumstances, it might be desirable for a
   BGP speaker to know both the next hops and the next-next hops of NLRI
   to make optimal forwarding decisions.  One such example is global
   load balancing (GLB) in a Clos network.

   [I-D.ietf-idr-entropy-label] defines the "Next Hop Dependent
   Capabilities Attribute" (NHC) which allows a BGP speaker to signal
   the forwarding capabilities associated with a given next hop.

   This document defines a new NHC capability, the Next-next Hop Nodes
   (NNHN) capability, which can be used to advertise the next-next hop
   nodes associated with a given next hop.
