ten steps of small LAN design
A few days ago I posted an amusing comment on Ivan Pepelnjak's always excellent Cisco IOS Hints and Tricks blog, and he found it funny enough to create a separate post. I'll repeat my ten step program here for future reference:
- Build everything at layer 2 because "it's simpler".
- Scale a little.
- Things start breaking mysteriously. Run around in circles. Learn about packet sniffers and STP.
- Learn about layer 3 features in switches you already own. Start routing.
- Scale more.
- Things start breaking mysteriously. Learn about TCAMs. Start wishing for NetFlow.
- Redesign. Buy stuff.
- Scale more.
- VMWare jockeys start asking about bridging across the WAN.
- Enroll in hair loss program.
