Software or PHP/PERL scripts for simple network management?

Does anyone have a recommendation of any software products either commercial or freeware which will import the ip routing table from one of my routers/switches and display it in a sorted manner? We just need an easier distributed method than logging into our Black Diamond and typing sh iproute sorted every time we need to find an available subnet.
