Standardmultihomed BGPsetup with minimal TE if I can help it. I am starting to run intoproblems witha full gigabit port on Level3 and only 100-200mbps on Cogent at thatcolo. Itried padding, I even tried 65000:2906 bgp community, but it seems likeif ourlevel3 port is up NetFlix chooses it solely. How can I load balanceNetFlixtraffic across my two ports so that I am not paying for overages and/orforcedto up to a 10G port immediately? I have 3 other providers at that coloandcannot find any mix of bgp tricks to get some of it thru our otherproviders.I notice AS2906 has a localpref of 86 - odd ... The 108.175.47.0/24 block seems to be using as 2906 so I thought a65000:2906wouldn't announce those prefixes to them at all. I have about 10prefixes beingannounced so I could implement a no-export on some of them to loadbalance butthat doesn't work.
