well you don't always have to put frame-relay map or interface dlci command to configure frame-relay. The most basic one could just be int serial0 ip address x.x.x.x y.y.y.y encap frame-relay exit The router will do the mapping of dlci to ip address by using inverse-arp dynamically.
and as far as I know the router will maintain some sort of cache for this mapping you can check it out by using the command sh frame map. >From: "MADMAN" >Reply-To: "MADMAN" >To: [EMAIL PROTECTED] >Subject: Re: Serial Line is up and line protocol is up ANSW [7:27930] >Date: Tue, 4 Dec 2001 12:31:30 -0500 > >not sure what an ip address has to do with LMI nor inverse arp as a >map or interface dlci x will work just fine too.
