IPv4, standard termination routers (7206VXR), DHCP, no router CPE 
required, no request limitations. We'll have equivalent in IPv6 with 
DHCPv6, except we route prefixes for routers, but that won't effect the 
mac tables.

Router 1: 1233
Router 2: 1012
Router 3: 2198

and so on (just random routers). I don't see these numbers as being an 
issue. The router choice of the ISP is often a factor of number of 
customers, throughput, and desired feature sets/flexibility; which is 
why we run multiple processor based routers. I can handle more customers 
on a hardware based platform, but I also get much better support for the 
100s of thousands of ND/ARP tables and run the risk of hardware not 
supporting a feature I need.

Customers are often likely to get a router for their location, 
especially if you aren't providing wireless in the stock CPE; though I 
do have a few regions which issue stock CPE with wireless, fully bridged 
(no routing). Customer's choice.
