This is a follow up post to my last OSPF post about repairing area 0. In the comments section Ray asked me what we can do if we have a scenario where we have another area that is discontigous. In
Repairing a discontigous area 0 in OSPF
First start by looking at the diagram above. This is a scenario I ran into while doing my mock lab. It is pretty obvious that we will have issues with OSPF since area 0 is discontigous. You should be able
First mock lab done (Cisco 360)
So I had my first run at a mock lab (Cisco 360). It was not a great score by any means. I got 59% on the TS and 49% on the config. Still, it does show that I’m not THAT

Frame-relay IPv6 speed drill
Going for the lab we need both speed and skills. I made a simple IPv6 frame-relay lab that should test your speed. Time yourself and post your time to configure in the comments. Just by looking at the time I
Followup on multicast helper map
I had some requests for the final configs so I have fixed those. You can download them here. Also I had some issues getting the traffic through but thanks to my helpful readers like zumzum I now have it figured
Multicast helper map and how to verify multicast
