IPv6 ASN question

Hi Harold,

We were just issued our IPv6 address block by Arin, and it came with three ASNs. Could you provide any information on why there are three (instead of just one)?  Also, would I use one of those ASNs for my EIGRP routing on the inside or are those only for use with my BGP routing to our ISPs? (in other words, can I use a private ASN for EIGRP on the inside or will that mess things up?) Thanks much!

EIGRP AS number isn't related to BGP AS number.  As a general rule, to communicate with other ISPs via BGP you need a public AS number given to you by someone like arin.  You can pick whatever AS number you like to use for EIGRP.  Your EIGRP AS number has no bearing whatsoever on your BGP AS number.  They can be the same, or they can be different.
