Hey all,
In early October our traffic levels from NetFlix went from about half Level3 and
half Cogent - pretty well balanced - to all on Level3. Standard multihomed BGP
setup with minimal TE if I can help it. I am starting to run into problems with
a full gigabit port on Level3 and only 100-200mbps on Cogent at that colo. I
tried padding, I even tried 65000:2906 bgp community, but it seems like if our
level3 port is up NetFlix chooses it solely. How can I load balance NetFlix
traffic across my two ports so that I am not paying for overages and/or forced
to up to a 10G port immediately? I have 3 other providers at that colo and
cannot find any mix of bgp tricks to get some of it thru our other providers.
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 a 65000:2906
wouldn't announce those prefixes to them at all. I have about 10 prefixes being
announced so I could implement a no-export on some of them to load balance but
that doesn't work.
Thx,
Sam
