I use rancid for config gathering among other things for the Cisco side of the network here. I think for what I am trying to do it would be more of a headache to try to tie in Rancid. I am in the middle of a large network redesign and am trying to gather and correlate data; NAT, Layer3 ARP, Layer2 MAC, VRRP/HSRP/GLBP and a handful of other things all living on F5, Cisco, Foundry/Brocade, Juniper, Radware, Extreme, and Secure Computing. Most of these devices are unsupported in RANCID. I thought about it and then realized it might just be easier to start from scratch. No I am not stretching the truth... We really do have that many different vendors in our network. Anyone have an easy button? :)
