If you are going to have each site connected separately to the outside world, you will want a /48 for each site. If you are going to aggregate them internally, you can use whatever you want, although you should be able to get a /48 for each site anyway. You don't want to announce anything longer than a /48 to the outside world. -Randy -- | Randy Carpenter | Vice President - IT Services | Red Hat Certified Engineer | First Network Group, Inc. | (800)578-6381, Opt. 1 ---- ----- Original Message -----
Hi all, What IPv6 prefix lengths are people accepting in BGP from peers/customers? My employer just got a /48 allocation from ARIN, and we're trying to figure out how to support multiple end sites out of this (probably around 10). I was thinking about assigning a /56 per site, but looking at the BGP table stats on potaroo.net [1], it looks like this is not too common (only .29% of prefixes). Thoughts? Thanks, --Richard [1] <http://bgp.potaroo.net/v6/as2.0/index.html>
