Hi, "Inverse arp" is automaticaly disable with frame relay mapping statement. In point-to-point sub-interface you must define interface dlci what you will use. Best Regard thierry >>> Ronnie Royston <[EMAIL PROTECTED]> 15/01/01 03h55 >>> Why wouldn't it? Inverse ARP is a dynamic mapping, 'frame map' command is a static mapping. If I remember correctly, You must disable inverse arp on the major interface even if you have 'no frame inverse' on the point-to-multipoint subinterface to actually disable it (is that what is suprising you, maybe?). Frame inverse arp works for everything but point-to-point subinterfaces. For these interface types, it is not needed. -----Original Message----- From: Nigel Taylor [mailto:[EMAIL PROTECTED]] Sent: Sunday, January 14, 2001 6:48 PM To: Cisco Group Study; Chuck Larrieu; CCIE_Lab Group Study Subject: Frame Relay...Inverse-Arp..? Hi All, I was working through a number of frame relay lab and made = some pretty cool observations. The big one being that I had Inverse-Arp = working as well while using the "frame-map" command. Everything I know = tells me this shouldn't be but it works. I reloaded the routers and the Inverse arp worked. Even after shutting = down the interface and bringing it back up the Inverse-Arp still worked. = =20 Anyone got any thoughts on how this could be working....?
