Thread Index [isp-bgp] RE: Questions about a Cisco 6509
I would agree that the 6509 /w SUP2u's/512MB ram would be an excellent
choice given your situation. I would stay away from the SUP720 until any
potential major bugs are worked out. I am very happy with the
6509's/SUP2U's on my network running Native IOS. However, I would urge you
to consider the used market if cost is an issue. Cisco will also sell used
("reman") equipment at a substantial savings...(the same warranty's apply,
basically as good as new).
As far as non-Cisco vendors are concerned, I think it's wise to stick with a
platform that is widely supported and proven.
