Hi, I apologize if this has been asked before. I work for an ISP that started very small (hundreds of T1 and 56k customers) and has grown very large in the last few years (thousands of T1 customers, as well as DS3 customers and OC3 customers). We currently use an IGP to route between our distribution routers and the CPE routers we manage. This has historically worked very well. We have recently begun running into scalability issues however. We have some distribution routers that have over 1000 T1 interfaces on them. This is causing some problems with stability in that edge IGP. Does any other service provider use an IGP all the way to the customer for non BGP customers or are we the only one? I have a feeling we maybe are.
So, if customers bounce your IGP churns away? And customers have access to your IGP data (provided they break into the CPE, which is trivial, eh?)
