Re: NSPs and filters

I'm not saying UUNet should install whatever filters I want on their routers. I'm just saying the net would be a MUCH nicer place if NSP's all did ingress filtering on their customer connections. If current routers can't handle the load this would create, then NSP's need to find vendors willing to deliver the necessary power, or they need to rethink the way they design their networks.

Most of my customers have customers who in turn have customers, not a few of whom are multi-homed. Same for UUNET, ... So, at POP X, I take in maybe 100 prefixes, with maybe 1000 at some POPs. How do I build and maintain that filter list, and how long does it take each packet to get through it with a router that also does real routing? randy
