I want to thank Joe again for the great lecture on IPv6. One thing Joe sure did right is to destroy the fear and prejudice I had about this topic. I hated even to think about subnetting in hex and all things that go along with it. :) My brain is automatically doing all sorts of weird stuff with ipv4 addressing but here it's all 128-bit hex... Killing combo - at least that's what I thought. :) Anyway, we had fairly complex topology in the lecture and all seemed so clear and the connectivity was made without much fuss.

Otherwise redundant links would not be possible. You can see this for instance by setting up two ethernet connections and running ospf on both ------Original Message------ From: Bojan Zivancevic Sender: [email protected] To: CCIE OSL Subject: Re: [OSL | CCIE_RS] Today's V-Lecture on IPv6 Addressing/Routing Sent: May 18, 2010 12:59 PM Regarding OSPF flapping... I think it is related to router-id issue. Both routers see two neighbors with the same router-id coming in. I saw that a while ago in some ipv4 lab. The same happens if two routers that want to become neighbors have the same id - I think ospf would behave in the same way. Best Regards, Bojan Zivancevic Network Engineer ---- Comutel d.o.o.
