Dear All, I will implement Frame Relay connection from branch to head office. I have idea to provide back up connection to minimize down time if network failed. The scenario is,..when FR connection as primary goes down. The back up link by using Dial Up in int asycn will automaticaly dial to head office which already provide modem there. Does anyone can help how to build that scenario. Many thanks for your helps Rgds, Erwin **NOTE: New CCNA/CCDA List has been formed.
