Section [22.214.171.124] specifies an algorithm that routers ought to use when selecting a next-hop for a packet.
This appendix provides historical perspective for the next-hop selection problem. It also presents several additional pruning rules and next-hop selection algorithms that might be found in the Internet.
This appendix presents material drawn from an earlier, unpublished, work by Philip Almquist; Ruminations on the Next Hop.
This Appendix does not specify any standards or requirements.
