Usually I start off a lab by building the topology itself – adding all the nodes, adding the network modules to each node and then connecting them all together. When that’s done I boot the topology in the cloud, figure out a proper addressing scheme, open a console session to each device, configure the Ethernet interfaces according to the scheme, configure loopback interfaces for router IDs and LAN simulation, configure global settings for lines, IPv6, logging etc. and then finally enable one or more routing protocols on all nodes for end-to-end connectivity.

What if I could outsource these initial router configuration steps? Just create a topology and off I go?

Unable to find a proper *aaS provider or Facebook app for this particular need, I built something that solves just that:
