- Link-state tracking, VMware ESX and You ´ NoSwitchport.com –
With the increased push towards server consolidation and deployment of VMware, the ìrouted is betterî mantra has become muted by the layer 2 requirements of virtual machine mobility.
Great explanation of WHY link state tracking works for VMware. It enables a neat design where there is no L2 loop from Core/Dist to Access Layer.

- HP Blogs – Why should SMBs care about network standards? – The HP Blog Hub –
Did you play with building bricks when you were a child? I did and I really enjoyed creating objects like a house, a boat, a car or whatever my imagination demanded. My favorite bricks were Lego, because they fit so well together. Just a few pieces in different sizes enabled me to do marvelous thingsñI think. What I really hated was the fact that I could not combine my Legos with building blocks from another brand. This is where my dislike of things that donít fit together perhaps started.
Great metaphor for standards in networking. Compare this with Storage vendors whose products are standards compliant, but must be validated to have support. I’m asking: Why ? Are their standards not very good ?
- Fragmentation Needed: Router console via bluetooth – Chris Marget talks about his Bluetooth console cable – it’s a work of art.
The BT232B pairs easily with both Windows 7 and OSX. Both platforms install it as a locally attached serial port: COMx in Windows and /dev/tty.mumble in OSX. Its baud rate defaults to something other than 9600 baud. I configured it once, and have not had to reconfigure it, so either it remembers its settings, or it’s taking cues from my terminal emulator software.
Only problem ? Windows. Still not working properly after twenty years.
The Windows 7 bluetooth drivers are kind of terrible. If I’m linked up with the device and put my laptop to sleep, I need to delete the port and re-add it in the control panel in order to get it working again. Under OSX it just works.
- Skype 5 for Mac, but without the whitespace – Stylesheet for Skype 5 for MAC. Makes the chat window livable. Still ugly, but livable. barely. Actually, no. I hate Skype 5. It’s ugly.
- Chewtoy’s Technical Musings: Fear and Loathing in IPv6 –
In conclusion I concur with Greg and with the IAB that for IPv6 deployments in enterprise networks today PI is the only workable solution. Admitting this still makes me feel uncomfortable.
Russel is pointing out the the IAB in RFC5902 also agrees that Provider Independent Addressing in the way to go.
