Re: AS701 peer local-pref?

[Jared Mauch <jared () puck Nether net>]

        they could just be relying on as_path+bgp bestpath

        but yeah, i personally prefer a model of
localprefs in this order (highest first obviously)

        customer
        peer
        upstream
        
        this puts traffic across links that you get paid for,
you get for (free?) a lower cost than upstream/transit then
the most expensive link.
