as-out metrics

Daniel,

Viewing the previous exchange, it looks like you agree that the routes export
metric is useful information and it needs to be somewhere.  The difference is
where it should be put, in as-out or put it in a new attributes. 

It seems that metric out fits naturally in as-out for the following reason: 

as-in describes how an AS import routes including what routes to import and
what preference it accept them.

as-out describes how an AS export routes including what routes to export and
what metric it announce them.

Both perference in as-in and metric in as-out are enforcable by the AS.

So it actually make as-out more symtric to as-in by adding export metric.  And it
also fits the definition of as-out.  

Create a new attribute of bgp_metric like you suggested has someside that is: 

ASs have to repeat what described in as-out in order just to put metric with the
different set of routes it advertised.   It is really redundant to as-out.
