Frame-Relay and PPP Help

Hello I am trying to prepare for my skills based assessment and have run into a snag. I am configuring 3 routers to simulate a Frame-Relay and PPP network, Frame-Relay is configured on ISP and Sydney routers while PPP is configured on both Sydney and Auckland routers. Pings work from Sydney to Auckland, ISP to Sydney, but NOT from Auckland to ISP. I have checked my configurations over the best I could and still cannot find the problem. If anyone has any ideas please let me know. Thank you in advance for the help.

You are running routing protocols that use multicast addresses for their operation but your frame relay maps are missing the broadcast keyword to allow that to work. Add the broadcast keyword to the frame relay map statements and see if that causes the failing pings to start working.
