Hi Michael, I'm curious as to how that is working....
Did you no shut the interface prior to entering "encapsulation frame-relay" or after? Do you have dynamic frame-relay maps? (show frame-relay map). Otherwise you don't have an l2-l3 mapping. Also, you have clock rate xxxx is this back to back or going via a frame switch? Clock rate sets the interface type to dce and is superfluous if you are going via a switch. If its back to back you should also use frame-relay intf-type dce at one end (not necessarily the serial dce end, but its a good idea to keep it consistent) To summarise: I think you did "no shut" then did "encapsulation frame-relay" and then inverse-arp kicked in and learned all the dynamic l2-l3 mappings. After that you put in "no frame-relay inverse-arp" but by that stage it had already done its trick. Afterthought: I also see your "do ping" is from dlci config mode. Did you enter dlci information? There isnt any shown in the config. If you did then inverse-arp doent happen, but also other things will go wrong with the ip address on the physical interface rather than on the dlci. I'm not trying to be a pain but if your frame-relay is cactus then so is your ospf and you will see ridiculous neighbours pop up on dlcis that they shouldnt be and there begins the world of hurt...
