Hey folks...
I'm meeting with a customer tomorrow (service provider, rural telco) and we're pitching they move to a PPPOE platform most likely. But to be fair, I'm looking to draw up a comparison so they are "well informed" of the pros/cons. Has anyone done this? I came up with the following brief start: PPPOE vs DHCP PPPOE Pros ---------- Allows full authentication of customers (requires username/password) Allows control over customer connections (suspend accounts, create accounts etc) Easily assign static IP to customer (no MAC address or CPE information required) Assign public subnet to customer with ease (no manual routing required) IPv4/IPv6 fully supported on Juniper platform as required Usage tracking (GB transfer) from radius generated data PPPOE Cons ---------- Requires PPPOE termination router (Juniper ERX for example) Requires Radius server(s) to assign and track customer IP assignments/usage Customers require username/password to connect Customers require PPPOE client software or router to connect 8 bytes MTU overhead DHCP Pros --------- Simplistic - plug and play 90% of the time No MTU overhead, full 1500 MTU frame size DHCP Cons --------- No authentication occurs (anyone physically connected can use Internet generally) No user tracking without tracking customer CPE MAC addresses No usage tracking builtin to DHCP (GB transfer) There are several factors involved here. The first major thing is that we believe the customer wants to move towards caps on their customer usage (X amount of GB per month). Today, they are doing static IP assignments but the interesting thing is that the CPE they have control over today (Comtrend routers with DSL modem builtin). I know there's not always a good vs bad here but looking for opinions from folks who may have already done this comparison for a "boardroom discussion".... Thanks ;) Paul
