[Idr] FW: New Version Notification for draft-wang-idr-next-next-hop-nodes-00.txt

[Kevin Wang <[e-mail]>]

Hi,

We have published a draft for a BGP speaker to advertise next-next-hop nodes corresponding to a next-hop it advertises. At this moment, the main purpose for this draft is for global load balancing in the CLOS networks. We defined a new TLV in the “Next Hop Dependent Capabilities” attribute to single the “Next-next Hop Nodes”. We appreciate feedbacks from the IDR group.

Thanks,
Kevin

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.
