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
Are you talking about assigning /56s per POP, enterprise site?
If /56s are just in your iBGP..shouldn't be a problem. You're going to aggregate and just announce your /48 to your eBGP peers, yes??
If there are multiple indendent end sites then get a /48 for each of them. A /48 is for a SITE not a ENTERPRISE. -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: marka@isc.org
