Here are some quick notes I took after watching this video.

Some handy commands I use to save my time doing Cisco IOS XR labs

Remember: Default behaviors of Cisco IOS XR are there to secure your router even we forget to configure them. Never try to disable them on any production network!

For lab practice, however, security is not my concern at all. I list some of my handy configuration fragments to save me time when I do IOS XR labs. I hope they are also helpful to you!

Why should we turn off mobile phones when we travel in an airplane, Part 1

This video is funny. But some of the challenges from the passengers are quite true.


  • "90-Million -dollar aircraft can't ignore the signals from my 40-dollar iPod Shuffle?"
  • "Can I hold this plane hostage with my (Nintendo) 3DS?"
  • "How come the plane is not interfering with my phone?"
  • "Why don't other phones interfere my phone?"
  • "I just always leave my phone on and nothing happened?"

I think all the fears of "interferences to navigation" was because of some sound like this one.
