if you encounter problems is to go back to a single stack member, and disable all other stack members. Then test your PPP Multilink connections, and go through the usual Challenge Handshake Authentication Protocol (CHAP) authentication and interface configuration for errors in the configuration and so forth. If the configuration works, enable the other stack members, and then proceed as follows:

Make sure the Stack Group Bidding Protocol (SGBP) is up and running.

debug sgbp hellos

debug sgbp error

Debug PPP Multilink.

show ppp multilink

Debug Virtual Private Dial-up Network (VPDN) and Layer 2 Forwarding Protocol (L2F).

debug vpdn event

debug vpdn error

debug vpdn l2x-error
