[c-nsp] Looking for suggestions on how to link old colo with the new colo for routing purposes until new circuits are in place

[Dan Troxel]

The issue is we cannot advertise to the net any sub /24 nets. Thus, we need
to control those some how with an internal mesh - but the old and the new
locations are not physically connected in anyway (yet), except through the
internet.

I'm very new to this game, but from my understanding I will try. Please
correct me if I am wrong, or if I am misunderstanding the problem:

If you control all of the network routers, could you not advertise the
sub /24 nets across your infrastructure via iBGP, and then aggregate
them all together at your border routers that face the 100Mbps
connections and advertise them aggregated from there?

>From what I do know for fact, is that adding in any type of encryption
just to do routing adds a burden of overhead that is apparently not what
you want.

Or do I have this all wrong?
