I have three leased lines to the Internet and just bought a PIX 515UR. The vendor told me that one PIX unit would be enough to handle all three lines (each with different IP addresses) and supplied me a PIX with three Ethernet interfaces.
Now, he tells me that for ONE PIX to handle three different IPs, I'll have to get an AS number, run BGP on my Cisco 2501s. And that the 2500 is not good enough to run BGP - and to get more powerful routers.
Or buy two more PIXs.
I'm a newbie - please help me with how I should solve this one.
Thanks a million
