a lot of providers have their bgp/routing policy published somewhere online/in their community guide for instance, you can find L3's policy in their irr objects ( whois -h whois.radb.net as3356) there are also plenty of community guides available here - http://www.onesc.net/communities/ Christian On Mon, Aug 18, 2008 at 9:32 PM, Mike Lyon <mike.lyon@gmail.com> wrote:
Hello All,
I am curious as to the routing polices of the bigger providers such as ATT, L3, Internap, Qwest, Etc Etc... Is there a standard size netblock that these providers will accept? For instance, if customer "A" gets a /22 from ARIN and his upstream provider is ATT and L3, what would the smallest block be that those providers would accept from customer "A"? Would they accept something as small as a /24?
Thanks, Mike
