We are ISP and local-ir too, and we have 4 links (bgp) to other ISP. We are thinking about dividing our network in two AS. Reason for that is to divide network and customers so we could announce AS-es different to different bgp peers. ... (snip) Is it possible to ask another AS Number from RIPE within existing IP space or with new IP addresses allocation?
According to the RFC 1930: An AS is only needed when you have a routing policy which is different from that of your border gateway peers. Here routing policy refers to how the rest of the Internet makes routing decisions based on information from your AS. Since your new AS will use different prefixes and different routing policies than your current AS, that may be a solid argument to ask the regional registry to assign you a separate number. At least - all huge ISP's in the world have several AS numbers. ;-) Regards, Beri .-------. | --+-- | Berislav Todorovic, B.Sc.E.E. | E-mail: BERI@etf.bg.ac.yu | /|\ Hostmaster of the YU TLD | |-(-+-)-| School of Electrical Engineering | Phone: (+381-11) 3221-419 | \|/ Bulevar Revolucije 73 | 3218-350 | --+-- | 11000 Belgrade SERBIA, YUGOSLAVIA | Fax: (+381-11) 3248-681 `-------' --------------------------------------------------------------------
