PPP multilink problem on BRI interface

[moses12315]

I have a problem for the last 1 month. I have 2 routers connected with ISDN(2 channels) on a WAN link. When i enable ppp multilink on both interfaces then i have serious problems and the link actually does not work. I attach some of the configuration also a diagram.

I appreciate any help or comments.

Thanks a lot

Moses.

Have you tried shutting down and restart the interface of both routers after you apply "ppp multilink"?

It could be an LCP problem, where introducing "ppp multilink" to an existing connection may not work as multilink is triggered during the call setup.

Here's a nice troubleshooting workflow link from Cisco http://www.cisco.com/en/US/tech/tk801/tk379/technologies_tech_note09186a0080094bb8.shtml

Please post the debug output.
