Hello,Is that okay to use Same AS number for the two different site on differentlocation?
To answer this specific question, Autonomous Systems should be topologically convex. This means, at the Internet interdomain routing (BGP) level, that packets cannot leave an AS in one place to get to locations in the same AS in some other place.
So, to put two sites on one AS, there should be an internal connection between them, which can be done through your internal network, by a direct connection, or by a tunnel. Traffic might come to the AS at either site, and has to be routed internally to get to the other.
See RFC 1930 and the material linked to in the other posts. Regards Marshall
as well as any good documentation or link or deployment scenario where I canfind the merging of two different AS into one AS? As well as what to do if I have an IP addresses as a service providerdependent block and want to migrate IP addressing to the IANA assigned ipaddresses? how can i achieve that? regards Devang Patel
