Video: Implementing VLAN-aware Bridge with OpenFlow
Reinventing the wheels makes little sense. Implementing old solutions with new tools might be in the same category, but at least it shows you the power and shortcomings of the new tools.
Building a VLAN-aware bridge in OpenFlow is thus a mandatory case study, and as you’ll see in the video from the OpenFlow Deep Dive webinar, it’s not as easy as it looks. For more details, watch the whole OpenFlow webinar (6 hours of in-depth videos), which you also get by buying Advanced SDN Training or ipSpace.net subscription.
CCDE Practical Training Demo Video
I have been delivering CCDE practical training for quite some time. Couple months ago I have started a survey for my CCDE training. 134 people voted and here is the results. From the votes as I understand, many people have been looking for a demo, sample videos from my CCDE practical training class. Below is the half an hour CCDE Practical demo video from my CCDE training.… Read More »

June “Network Toolset Challenge”
This month we are excited to partner up again with the crew over at Solarwinds for the June Network Toolset Challenge! Thanks toMy CLUS 2015 Schedule
I'm lucky enough to be heading to Cisco Live in San Diego this year to host customers from my area. When I'm not with a customer during the day I plan on attending these sessions:

Uh, the only reform of domestic surveillance is dismantling it
A lot of smart people are cheering the reforms of domestic surveillance in the USA "FREEDOM" Act. Examples include Timothy Lee, EFF, Julian Sanchez, and Amie Stepanovich. I don't understand why. Domestic surveillance is a violation of our rights. The only acceptable reform is getting rid of it. Anything less is the moral equivalent of forcing muggers to not wear ski masks -- it doesn't actually address the core problem (mugging, in this case).
Bulk collection still happens, and searches still happen. The only thing the act does is move ownership of the metadata databases from the NSA to the phone companies. In no way does the bill reform the idea that, on the pretext of terrorism, law enforcement can still rummage through the records, looking for everyone "two hops" away from a terrorist.
We all know the Patriot Act is used primarily to prosecute the War on Drugs rather than the War on Terror. I see nothing in FREEDOM act that reforms this. We all know the government cloaks its abuses under the secrecy of national security -- and while I see lots in the act that tries to make things more transparent, the act still Continue reading

IPv6 DMVPN Routing
In our last article we looked at IPv6 over IPv4 DMVPN configuration, where IPv4 transport was used to tunnel IPv6 traffic. In this blog post I would like to show you how to deploy pure IPv6 DMVPN network, and even more importantly, how to enable one IPv6 Routing Protocol over another in the Cloud.
Since IPv6 will be now also used as the underlying transport, the overall configuration of the DMVPN devices will be a little bit different from the previous example; also note that our topology was slightly modified :
Key thing here is that NBMA addresses are no longer IPv4; basically IPv6 is used everywhere, which means that our mappings on the Spokes will be always referring to v6 information.
Let’s start our configuration. We will first configure our Hub (R3), then the Spokes (R2, R4), and finally enable routing on the Overlay network. Since IPSec is optional, we will not be using it in this example (note that to protect IPv6 packets IKEv2 would have to be used, not IKEv1).
R3 (Hub) configuration. Again, everything is IPv6, including the tunnel mode. Don’t forget that link-local addresses must be always hard-coded on a given Cloud, on every device Continue reading
