I am using RB5009 with PPPoE. If by any chance the link to an intermediate switch fails and comes back the pppoe doesn't dial up automatically. The state of the PPPoE interface is disconnected.

I don't believe you.
Proof?

The pppoe tunnel, should and will go up as long as the pppoe server responds to the discovery messages of the pppoe client and all the stages get completed successfully.

You want me to disrupt the connection to show you proof?

Yes but that should put the pppoe interface into connecting state but it isn't.

I'm guessing you have some logs that support your statement, sorry, I don't want you to disrupt your network intentionally.

Here are the attachments.

I have an Internet connection over PPPoE and when I get disconnected I can connect again but have to wait till the server offers a reconnect. This is a window that passes my connection and can take up to 7 minutes.

You can press in winbox the blue-V twice, to force a reconnect but that does not work brcause I have wait for the window to pass by.

Pictures are nice, but they don't say much here.
Check some.. you know, logs. Like I've said above.

Here are the attachments.

Turn on the PPP logging and post the logs. Those attachments don't show much that can be used for diagnostics.
