Re: PPPoE session from Montreal terminating in Toronto???
If I understand you correctly it is normal for the session to terminate in Toronto. I guess it doesn't make a huge difference when interleaving is active, at least if it has high interleaving depth, but it makes a difference. A return trip Montreal-Toronto should be about 10 ms and adsl with interleaving adds about 40ms. In the case of accessing something in locally in Montreal the Toronto trip makes a difference since it might add up to 20ms, but it doesn't make up for a 100ms difference as you say.
Going fast path versus interleaving is always a trade off. Also the interleaving depth is something to consider. For a normal Internet access pack errors aren't that critical and it can actually benefit in terms of speed even with a higher error rate since a lower delay might go easier on tcp. For a multicasted tv service packet errors are a disaster and a high interleaving is therefore a must. So what I'm saying is that in my case fast path would be worth the risk. If you don't mind changing it I would want to give it a try.
Except for the somewhat high delay the connections has been working perfectly after the Bell "miss configuration" was sorted out. Thanks for the hard work of keeping us happy.

| BTW, I saw on one new activation in Montreal - friend of mine who is Acanac user, the technician logged with his PPPoE and the ping to NY was 28ms, Then he did the same test with customer's PPPoE (Acanac) - it showed exactly 28ms, so I dont believe the PPPoE itself makes difference.
Let me create a fast path query for you.
Note - the upstream shows 512 not 800 but you are very close to CO. It could be an IKNS one.
