Hello, Please advice what is the best practice to use IPv6 address block across distributed locations. Recently we obtained our PI /48 from RIPE. The idea was to assign partial slices from this block to different locations (we have currently 3 offices in Europe and 2 in USA). All locations are interconnected with static VPNs. Each location is supposed to establish BGP session with local ISP. Partial prefix /56 + aggregate /48 (with long AS PATH) are to be announced by each office. The problem we ran across is that ISP in US does not wish to accept prefixes longer then /48 from us. Need your advice: is this normal to distribute /48 by /56 parts across locations or should we obtain separate /48 for each of them? Or maybe we need /32 that can be split into multiple /48? Anyway we are not ISP so /48 looks quite reasonable and sufficient for all our needs. Thank you. Dmitry Cherkasov
