I've been thinking of how to solve the "problem" of knowing what adresses are routed or not in our IGP. Does anyone know of a utility that you can feed a "show ip route ospf" or perhaps via snmp someway, that'll display what part of the IP space there is a route for or not, perhaps divided by /24 or /19 or something. What I was thinking of was to create a gif, with one pixel per IP number, so a /30 route would show up as a 4 pixel line etc. A /19 would then be a block of 256 times 32 pixels, where one can fairly easily see what IPs are being routed or not. It seems to be a common problem that link nets come and go and are not being reused.... Any good ideas? -- Mikael Abrahamsson email: swmike@swm.pp.se
