PPPoE bridged / routed and PPPoA on ADSL
Karl
I'm working on a linux based ADSL modem/firewall and see other
products on the market that say "PPPoE Routed", "PPPoE Bridged", and
PPPoA support.
My question is: What is PPPoE routed?
Two such examples are:

PPPoE bridged is simply rfc2516 which is a PPP link over a RFC2684
bridge Section 5.2 for LLC or Section 6.2 for VC MUX. I have no
problem with this, as this easily works in linux.
PPPoA is simply RFC 2364 and i have no question about that.
Now what is PPPoE routed? If it were a routed atm link like in
Section 5.1 of RFC 2684, the way i understand it is that with Routed
RFC2684 (Section 5.1) There are no Ethernet packet headers just
IP. So true PPPoE discovery described in RFC2516 will not work.
Could it be that PPPoE routed is just a marketing term, and in that
case "PPPoE Routed" == PPPoA ?
Any clarification would help me.
Thanks.
