Guys,
I've encountered the same problem too. Configured 4 routers for
frame-relay on the physical intf & left mapping to default of dynamic.
"sh frame map" doesn't show the dynamic discovered maps. Was like this
for a few minutes then decided to just reboot the routers. Sure enough,
the mappings appear _after_ the routers were rebooted. I didn't spend
much time troubleshooting this coz I was on a rental. This was on one
of the IE Lab (forgot which one now but it was lab 2-4) and using
RackTimeRentals router (think they were 3640s on 12.2T(something)).
Its probably one of those Cisco IOS "features"....
