Finished Soup-to-Nuts!
I finished Narbik’s book today. Pretty happy with that I might add. Certainly picked up a few gotchyas on the way through there. I just hope I remember them all for the upcoming months. Tomorrow I will go over the things I had trouble with on the InternetworkExpert CoD. Then I will repeat those sections of soup-to-nuts again and see if I do better.
One thing that has an incredibly high suck factor is the fact IPv6 does NOT WORK over frame-relay on my lab setup. I tried various methods of configuring (point-to-point, multipoint, frame maps) and nothing. I’m not that fussed though… I went through the answers thinking “I would type this line here” and there they were were I wanted them. A few things were different but thats all good. I havent done enough testing to see if it is a problem with the IOS I am using or if it is something else. My guess is IOS rather than being a dynamips/GNS3 problem because the frame mappings work fine with IPv4, as well as running IP across the links. So Im saying IPv6 IOS bug…
Im going to be generous once again and include the startup-configs I rewrote to work on my dynamips setup. I improved the configs as I went through the lab so some of them might not be a straight copy and paste, also some labs I did not edit as they had the same initial config as a previous lab. You will find these here and there. So if these things save you about 15-30 mins on the start of 90% of the labs I am sure you wont be complaining to me too much 
Now to open a bottle of some fine Barossa Valley Shiraz. mmmm
When I first set my dynamips lab up I noticed some irregularities when it came to frame-relay. For example the status of the PVCs was always up even if the other side was down.
What I did was to not use the “virtual frame-relay switch” but instead use a dynamips router and configure it as a frame-relay switch. When I did this frame-relay worked better and behaved like it should.
If you have not already done so you should give it a try instead of using a “virtual frame-relay switch” in dynamips. Perhaps that will solve your problem with IPv6.
