Me. Always shutdown the interface before configuring frame-relay ;)

Asunto: RE: Lab Tip question?
In that case, it's been my experience that the only command(s) needed are:
no fram inverse-arp
and
clear fram inarp (in case the interface was enabled before the previous
command was entered)
Anyone disagree?
