Hi, I'm Iljitsch van Beijnum. This page has all posts about all subjects.

Hue white ambiance dims all the way to 1%!

I got my Philips Hue starter kit two or three years ago. For those of you who have been living under a rock: Hue is a lighting system. The original Hue lights are power-efficient LED lights that can display a large range of colors: deep red, blue and purple as well as not-so-deep green and all the colors in between, which includes both cool and warm white light. There's a phone app to control the color and brightness of the lights. Unfortunately, the minimum brightness of the colored Hue lights is 5%, which is still relatively bright. This is especially annoying when you tell the lights to come on or go off slowly. The jump from off to minimum or minimum to off is somewhat jarring.

Cisco BGP identifiers

One of the tiebreakers in the BGP best path selection algorithm is to prefer the path learned from a BGP speaker with the lowest BGP identifier. So how are BGP identifier selected when they're not configured explicitly?

I always forget whether it's the highest or the lowest IP address configured on a Cisco router. Turns out this is remarkably hard to find in Google, but if you know where to look it's in Cisco's IOS command reference:

  • If a loopback interface is configured, the router ID is set to the IP address of the loopback interface. If multiple loopback interfaces are configured, the router ID is set to the IP address of the loopback interface with the highest IP address.

  • If no loopback interface is configured, the router ID is set to the highest IP address on a physical interface.
