This draft proposes to change the requirement that NUD can not 
retransmit more than three times, so that NUD can be more robust against 
temporary network outages.

Comments?

Title:		 Neighbor Unreachability Detection is too impatient
Creation date:	 2011-05-23
WG ID:		 Individual Submission
Number of pages: 5

Abstract:
    IPv6 Neighbor Discovery includes Neighbor Unreachability Detection.
    That function is very useful when a host has an alternative, for
    instance multiple default routers, since it allows the host to switch
    to the alternative in short time.  This time is 3 seconds after the
    node starts probing.  However, if there are no alternatives, this is
    far too impatient.  This document proposes an approach where an
    implementation can choose the timeout behavior to be different based
    on whether or not there are alternatives.
