Frame-Relay Initial Config

Frame-relay configuration can be tricky for those who are not familiar with.
Below should shows the frame-relay initial config..

before you start, please be noticed that:
1. this config are tested on 'LAB' environment only!
2. Router (config)#frame-relay switching, must be done before configuring interfaces.
3. makes sure all interfaces are in 'shut' mode before you start configuring. After config finished (and you're sure its correct), give 'no shut' command. 

so, here it goes:
