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
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.
