Cisco::VRF::Routing


Segregating WAN traffic to provide public internet access from a central location

We provide wireless internet in public areas in every office. For this purpose we provide cable internet, DSL, or dedicated T1 circuits. To save money and better control this traffic, we want to direct that traffic back through our headquarters' internet circuits. To do this we need a way to segregate this traffic on our WAN links for security and to keep it from overutilizing our WAN.
VRF and tunnels seems to be the answer.

VMWare::Internals


Some of our VM's still have the little ".flat" file that points to the real .vmdk file. It is bad when that file goes away.

Spent some quality time today working on my project journal site. I tried getting fancy with CSS to try to figure it out. I'm left with kind of a hybrid mess until I have more time to spend on it. I now have a table formatted page, but with an external style sheet taking the place of the STYLE section of my header.
