Being working with the National ISP .....

We last year got the request from one of our customer for BGP implementation
who provided us with the 2.X BGP AS number.

Our first reaction to this request was,WTF what is the ASno.?
On further inquiry the customer forwarded us with the mail which he received
as a formal communication regarding the AS no. allocation.

The APNIC had allocated the customer with this AS no., however we had to
turn down the request for the customer because of the 4Byte As no., since we
checked there wasn't any presence of the 4Byte ASN on the Internet nor was
any IOS release supporting it back then!!!

Regards,
Dara*
