Protecting the router control plane (RFC 6192): among other goodies, this document has a high-level description of high speed routers (sometimes known as layer-3 switches).
Is the network administrator role going away? I’ve heard the “something is going away” prediction too often in the last 20 years. We just end up doing other (more complex) things.
8 hints for using DNS more effectively – another great post from The Lone Sysadmin.
Yeah, I know, it never stops ... after being ignored for 15 years, IPv6 is becoming as hot as fabrics.
IPv6 Address Assignment to End Sites (RFC 6177) removes the stupid recommendation of assigning /48 to residential end-users. Finally we’re making some progress toward sanity. The /64-per-subnet one is still there.
Windows 7 seems to have weird problems with proper source address selection when using ULA addresses. The “use ULA internally to avoid renumbering” recommendation seems to be on hold ... (thanks for the link, @bobmccouch)
Project L3: Router Advertisements with scapy – teaching kids how to hack IPv6 networks as a science project.
Customer problems that could occur – nice list of things that can go wrong during IPv6 deployment.
IPv6 acceptance: Should you consider IPv4-style solutions? Good overview. It seems HP has pretty rich IPv6 implementation, but my cynical mind never rests.
“While SLAAC does not have as rich a set of parameters as DHCPv6, it is available whenever and wherever your router is.” Means you don’t have DHCPv6 server functionality in your routers, right?
Routing an IPv6 Core on Link-Local Addresses: you can run an entire IPv6 core on link-local addressed ... but just because you could doesn’t mean that you should. Yandy provides a good description of advantages and caveats.
Odd bits and pieces
Teaching kids how to have a discussion. Some adults obviously never got that lesson in the kindergarten.
Jose Leitao from the Initial Draft blog has asked me a few questions about Cisco certifications and my webinars.
