Cisco 857 Bridge Mode Help

Hi All,

I've been triying to configure a cisco 857 router to be in bridge mode that will allow my ASA to dial the PPPoE connection.  However I can't seem to get my config to work.  I've tied a few veriasions to get it to work but no success.  Could somboddy have a look at my config and tell me where i'm going wrong?

I get the following error when i connect to the console.

*Dec 27 11:56:46.660: %TBRIDGE-4-NOVCFLOOD: No VC's configured for bridging on ATM0

Hi Douglas,

Replace the encapsulation aal5mux ppp dialer in your PVC 0/38 with encapsulation aal5snap and try again. You may also need to add the protocol bridge broadcast along with the encapsulation command on that PVC.

Best regards,

Peter
