Edward's response nailed this one on the head. It has to do with the additional support/hardware required to support a BGP session. Granted, once a BGP session is established it rarely requires any tweaking, but I've spent hours troubleshooting a downed BGP session because the client's IPS signature update decided TCP/179 was malicious. You also have to implement additional filters to protect yourself from what your client can advertise. I'm lucky enough to work for a major ISP with pretty sophisticated filters built off the public route registry, but not all ISPs have this functionality.

The only thing that I can really think of is that the BGP sessions do take up extra CPU time and memory on the routing engine, so there is an additional cost to the provider in terms of needing more routers and/or bigger routers if they have lots of customers speaking BGP to them that they may not have factored in to their standard pricing.
I guess there is also some extra cost in terms of NOC staff and systems to monitor the sessions as well as providing any troubleshooting etc. that they wouldn't have to do with "standard" customers that are statically routed.

Hello everyone
I have been aggressively looking for deals in servers in Europe for anycasting. One thing which surprises me is the "setup costs" for BGP. Few providers quoted additional $50-100 which looks OK but a few of them quoted as high as $150 *extra every month* just for having BGP (no full routing table, but just default route pointing). Is there's any technical logic behind such heavy costs? I mean at the end of day we are all talking at layer 3 and thus it does not involves any hard connection/physical work. What other members pay for BGP setup costs?
Thanks!
