The Mess that is QoS in Layer 2

Since I looked at QoS Classification and Marking in the IP Header I figure I might as well finish it off and go over the same topic at Layer 2.  I kept the title, but in reality it's not that bad here.  There's a lot more consistency between the various Layer 2 technologies and things seem to translate pretty well.  The only real challenge comes into play when you need to start translating a Layer 2 marking to a Layer 3 marking, and vice versa.  I'll get to that in a bit, but first lets look at what we have to work with.

The Mess that is QoS in the IP Header

If there's a group of people out there that should be drug out into the street and shot it's the jackasses that designed QoS classification and marking in the IP . More specifically, the jackasses that decided we needed multiple definitions of the same bits and different bits at different layers. I sometimes wonder if the only reason that QoS classification and marking is this way is so that vendors, like Cisco, can test you on it.

At any rate, things are the way they are and we must learn it.

PeerIX Version 6: BGP and IPv6

I got involved in a project called PeerIX this week.  It's a group of guys that have all connected various routing devices together over GRE and/or IPsec tunnels to form a BGP network for learning purposes.  I got involved when a a thread on Networking-Forum about this group started thinking that this might be interesting to do the same concept with IPv6.  As I was one of the people that was interested here I am posting about it.

Shared IPsec with DMVPN and VRF-Lite

I did up a blog post for Steve over at Networking-Forum.com on a funky setup using Shared IPsec.  Here's the link for your reading pleasure.  http://www.networking-forum.com/blog/?p=1110

IPv4 Headers

I need to learn header formats better.  Tonight I started with the IPv4 header.

IP Directed Broadcast

I have this stupid blog, so I might as well put something on it.  And as you can tell from the other posts on this blog, I post on Networking-Forum.com.  The other day I broke down what an IP directed broadcast is.  You can read the full thread here, but here's the big post that had the most detail after the jump.
