I’d bet that 47787 is a paying century link customer. As such, despite the ugliness of the path, CL probably local prefs everything advertised by them higher than any non-paying link. I’m willing to bet 1299 is peered and not paying CL. Sending bits for revenue is almost always preferable to sending bits for free, so… Owen
