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...

Cheers,
Matt
