Two files, routers.csv that is basically the output of a walk of SHOW KNO CIRC: <fromname>,<fromarea>,<fromnode>,<fromcirc>,<toname>,<toarea>,<tonode>,<tocirc> Put cost on both sides in there we have a tool that can figure out path from A to B and from B to A. So how do I represent a LAN in your notation? (Psevdo node?) -P e.g.: CTAKAH,62,637,QNA-0,A1RTR,1,1023,UNKNOWN MIM,1,13,UNA-0,BENDER,12,2,UNKNOWN GORVAX,8,400,QNA-0,BENDER,12,2,UNKNOWN second file, end_nodes.csv (basically SHOW ADJ NODES): routername,routerarea,endptname,endptarea,endptnode e.g.: GORVAX,8,400,RHESUS,8,403 CTAKAH,62,637,COPOKA,62,4 sampsa On 9 Jan 2013, at 21:44, Ian McLaughlin <ian at platinum.net> wrote: On 2013-01-09, at 11:40 AM, sampsa at mac.com wrote: The output format of the mapper is very simple, and we plan to run it like once a week, max. So if people in non-auto-mappable areas just send me their info in the relevant format, I can use that to complete the map. Just tell us the format, and it will be done :) Ian
