For those without the WB in front of them, this task is in a frame relay lab. R2 and R4 are connected through a frame cloud. R2 was constrained from using INARP but was allowed to have a point-to-point sub-interface. But for R4, the task stipulates the following:
R4 should be configured without any subinterfaces. R4 is not allowed to use > "frame-relay map" commands. In the DSG, their solution was just to allow INARP to function on R4, knowing that R2 would answer even though 'no frame inv' was configured on R2. OK, I guess, but I had assumed inverse ARP was completely off limits, so instead I spun up the link with PPPoFR: R2: interface Serial0/1/0.1 point-to-point frame-relay interface-dlci 204 ppp Virtual-Template24 interface Virtual-Template24 ip address 150.100.24.2 255.255.255.0 R4: interface Serial0/0/0 no ip address encapsulation frame-relay frame-relay interface-dlci 402 ppp Virtual-Template42 interface Virtual-Template42 ip address 150.100.24.4 255.255.255.0 This seemed rather logical to me particularly because the next task indicated that the encapsulation should not be Cisco proprietary (which RFC1973-compliant PPPoFR would not be), and a later task (6.9) very obviously dictated a PPPoFR solution as well so this seemed to "fit." So my solution varied quite a bit from the DSG, which simply let Inverse ARP do its thing, but as far as I can tell I met the requirements and adhered to the constraints. Would I get the points on this task? _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com Are you a CCNP or CCIE and looking for a job?
