I have query about ISP Design.
Why some ISP`s (Ex: BT) using dual AS`es on their network?
What are the advantages of using more than one AS in the ISP
network?What can be achieved if you use more than one AS?
At my previous job, I ran a network that was composed of as many as 5 ASNs
for a while. The reason is that my employer acquired several other ISPs
in a fairly short time. Eventually, most of them were brought under our
'main' AS, but a few were still kept separate because the
expense/difficulties in getting sufficient internal bandwidth to those
sites made integrating them a bit more of a challenge.
