[AusNOG] Which NBN RSP are using PPPoE vs IP

[Jason Mikronis]

Hi Chris,

Forwarding is done like this - PPPoE - AAPT LAC - L2TP - ISP LNS

I have not checked with AAPT, but in a past life, forwarding at the LAC was done without checking passwords based on conditions (realm for example) and then L2F to the ISP LNS. If the L2TP session to the ISP was up, so was the PPPoE session. The only "issue" I can see is potential for too many MACs being presented to a single interface, but there should be no problems designing around that.

It is worthy of more investigation.

Jason

Unknown if the NTU injecting PPPoE Option 82 (AVC ID 000000xxx) get passed through on an L2TP wholesale (LAC/LNS?) to the wholesaler...

Useful; yes -- if you're the "first hop' in the L2 AVC/CVC; but 'one step back' via L2TP LNS may not pass. anyone confirm? (Never checked this myself..)

PCAP reveals all ;)
