EV: SOHO and SMB did use cheapest home GWs - it was enough for IPv4, even with
ISP redundancy. If you would like to upgrade them to something much more
expensive - good luck!
I did not investigate specifically Cisco, I am doubt anybody supports MHMP
properly, especially for the site that has a few subnets. IPv6 has fundamental
problems on the subnet level.
