Nodes attached to common multi-access link types (e.g., multicast-
capable, shared media, non-broadcast multiple access (NBMA), etc.)
can exchange packets as neighbors on the link, but they may not
always be provisioned with sufficient routing information for optimal
neighbor selection.  Such nodes should therefore be able to discover
a trusted intermediate router on the link that provides both
forwarding services to reach off-link destinations and redirection
services to inform the node of an on-link neighbor that is closer to
the final destination.  This redirection can provide a useful route
optimization, since the triangular path from the ingress link
neighbor, to the intermediate router, and finally to the egress link
neighbor may be considerably longer than the direct path from ingress
to egress.  However, ordinary redirection may lead to operational
issues on certain link types and/or in certain deployment scenarios.
This document therefore introduces an Asymmetric Extended Route
Optimization (AERO) capability that addresses the issues.  This document 
defines an Experimental Protocol for the Internet community.
