But I wasn't talking (A)DSL. DSL is last century. I am talking VDSL2/ETTH. Security model there is to only have ethernet and IP, no PPP/ATM, no L2TPv3 or PPPoE. Let's skip the terms BRAS/LNS etc. Anything that terminates tunnels is expensive (apart from GRE/IPV6IP which the 7600 seems to do very well, but I don't like tunnels. I like native). Most of the ETTH ports are 10/10, 100/10 or 100/100 (or even higher speeds) and 100/10 costs ~30 USD a month. L2TPv3/PPPoE is not an option.
I may be missing something. "only have ethernet and IP". Why is plain-ethernet with each subscriber provisioned in a separate router's vlan subinterface insufficient? There is no security issue because each subscriber only sees its own traffic. -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds." Systems. Networks.
