I have a VERY novel idea for you all and since noone has mentioned it,
here goes:


NOC----------Management Network---------SSH Drone
                                        | | | |
                    Serial Lines ->     | | | ---Router1
                                        | | |--Switch1
                                        | -Router2
                                        -Switch2


I know.  It's just too simple and it scales so very well so, it MUST be a
bad idea.

Even if you don't have a dedicated management network, you just put a box
that speaks SSH out there with serial access to your routers/switches.

If you DO have a management network, you connect that to it as well.

No matter what, you're secure to the SSH drone and if someone is in your
cabinets tapping the serial lines, you've got big physical security
problems to deal with and you had might as well flat out give up on
network security.

A Force Recon colonel once told me, "If it's a stupid idea, and it works,
it must not be a stupid idea."
