If you block all link local then off course ospfv3 neighbors will go down. Since link local addresses are not routeable so I don’t really see any reasons to block it. No only ospfv3 but you will also block neighbor discovery packets which provides ba...
It's a crazy idea but doable take a look at the following feature of OSPF:http://www.cisco.com/en/US/docs/ios/12_4t/12_4t15/ht_osmch.htmlIt also depends on what type of topology are we talking about. If its hub and spoke then 300 neighbors would be ...
It's not a strange behaviour, it is by design. Imagine someone configures a loopback and ospf automatically resets the adjacencies and re-originates new LSAs. So to keep the protocol stable it does not change the RID immediately. Clear ospf process s...
If your ISP is IPv6 ready the all you have to do enable IPv6 on your end and establish routing between you and ISP over v6 and that's it. I do not see a need for a tunnel in this case unless the devices between your gateway and your end devices are n...
Thanks for the info. Let me take this back to Cisco press. But aside from what is written in this book there is nothing proprietry about totally stub and it will work with any vendors' router without any issues. If you read RFC 2328 section 12.4.3.1,...
