MPLS and the Next Hop

This week I discovered that in all my labbing it would seem that I have never tried to run L3VPN MPLS over a Frame Relay hub and spoke configuration using OSPF and the provider IGP with a broadcast network type.  The reason that I know I’ve never done this before is because it just doesn’t work.  This seems like a sneaky little scenario for a TS task so here’s what things look like should you ever encounter it.

IPexpert IOU Topology

IOU has been leaked.  L2IOU has been leaked. It was only a matter of time before someone did this...  Might as well be me :)

Here's a NETMAP file that recreates the IPexpert CCIE R&S topology, and a wrapper script to start it. And as my special gift, a bash script to convert the config files provided by IPexpert to a format that (L2)IOU can work with.

I might do up some diagrams at some point, but for now you'll have to figure it out from these text files. 

Enjoy!

IOU Lab Topology #2

As I mentioned in my first IOU topology post I more frequently use another topology that has turned out to be better suited for my labbing needs than my first attempt.  Well, here is that topology.

IOU Lab Topology #1

Some time ago Cisco's IOU was leaked out to the web.  I was able to get a copy (don't ask where, I won't help you) and have managed to get it set up on a spare box at home.  There are a couple of really good tutorials on the Web that explain how to get it set up and working and how to build a lab topology.  I've built two topologies so far that I use to lab things up when needed, and I'd like to share the first with you now.
