    You don't BGP peer with an ISP without a very good reason for it. You will not be able to do it over FIOS

    They have a business class FIOS but it looks like they won't let you peer even with this.

    You need a strong business case to warrant BGP peering.... having a business internet service isn a strong case....

    ISPs are happy to just install framed-routes via radius or simply have static routes pointing to the CPE..... as it is their IP space....this ensures the reachability for you...and ensure less administrative duties\problems for them....

    Now if you have your own IP space....perhaps they might let you peer via private AS to them. (Possible.... but again ISP might just announce your space for you, if the block is large enough...and point a static at your CPE)

    Otherwise typically requirements for BGP peering between customer and ISP are customer has their own routable IP space, Own registered ASN and requires dynamic reachability\redundancy via being multi-homed to more than one ISP

    Speaking from experience APA is more than correct! When I worked for "a large financial organization" we had to submit to multiple discussions with AT&T before they would let us peer our public AS with them. In the end even though we owned the IP space (Class B), we had to use a combination of public and private BGP and only after satisfying the requirements of both their Network Architects and Security engineers did they let this through.

    Good luck!

    Time Warner required you to own a /24 or larger block and have your own AS number as well as fill out a justification form stating the reason for the peering. If you didn't "need" the BGP peer to operate, then you would be denied and just routed regularly.

    I think “very senior” gets stuck in there because the last six yahoos that applied for the position couldn’t tell a packet from a Snickers bar.

    I have not failed. I've just found 10,000 ways that won't work.
