AS_PATH length and route selection (WAS: Strange BGP announcement)

|  This, of course, leads to many, many other questions (such as the
|  possibility routing loops caused by different local policies as was seen
|  with implementations of BGP4), but few of which are of a truly operational
|  issue.  So I will apologize for starting a thread based on mis-information
|  and go back to my cave.

Different local policies should all be reflected in the LOCAL_PREF, which
should be distributed to all nodes within the domain.  This should lead to
consistent decisions within the domain and thus should avoid stable
forwarding loops.
