Hi,
First of all what you are asking is a bit confusing. If the lab asks you to
disable inverse arp and the routers should learn dlci's dynamicaly then
thats not possible as far as i know. In this situation you must configure
the hub router interface which is R3 subinterface as multipoint without
disabling the inverse arp feature. The router might learn a lot of dlci's
which you can verify through ' show frame-relay map ' command. Then what you
do is staticaly disable the dlci's which you do not need i-e ' no
frame-relay inverse-arp ip 213 ' , this way you will have only have the
dlci's pointing to R1 and R2. Same thing you do on R1 and R2 without
disabling the inverse arp and blocking the dlci's which you do not need.
I hope this works for you.
Regards,
Ahmed Ejaz.
