I was recently asked whether or not I preferred to use a router redundancy protocol like HSRP, VRRP, or GLBP, or stack switches together to form a sort of “virtual router”, and use that for redundancy. Just like anything else, the immediate answer is “it depends”, but there are a few things to remember when considering a redundant design with your routers or Layer 3 switches.
First, redundancy protocols can be found nearly everywhere.

First, I’d like to thank you all for continuing to read my thoughts these last few weeks. Some already know that I passed the CCNP ROUTE exam this past weekend, and that has slowed my ability to write consistently. Fortunately, I laid that beast of an exam to rest and I get to focus on bigger, better things.
I’ve been working a project for the past few weeks that’s involved the integration of HP and Cisco networking equipment.

I recently listened to Packet Pushers Show 72 on “How we are killing the internet” and want to voice my thoughts on the topics discussed.
The majority of the conversation circled around IPv6 adoption, and the state of the internet in light of the existence of tunneling mechanisms being used. Ivan mentioned that we are destroying the internet with all the tunnels (PPPoE, PPPoA, 6to4, 4to6, 6rd, etc) and translation points.

I had heard of CloudShark a while back but was reminded of it by a recent Packet Pushers article. For those that haven’t, CloudShark is a new product that basically claims to be a cloud-based capture file (such as from Wireshark) archiving solution. Viewing the main CloudShark website, you’ll be unable to miss what is obviously their big pull - CLOUDSHARK BRINGS YOUR CAPTURE FILES TO THE CLOUD OMGZ!!! (Did the fact that those words are at the top of each page on their site not give away their enthusiasm?

I was able to watch a good chunk of the morning session of the OpenFlow Symposium in San Jose. The stream was having issues at the beginning of the afternoon session, plus I was pulled away for other issues, so I was only able to watch the morning session. I’d like to provide a bit of a write-up from what I was able to catch, and point out some of the highlights that I took interest in from the day’s speakers.

I’ve been trying to get more into networking message boards like Networking Forum and TechExams.net lately. It’s a great way to get in touch with fellow packet lovers and gain some interesting perspectives along the way. In fact, it’s great for anyone in networking, whether you’re a hardened veteran or a newbie - there’s usually a place for you in at least one of these sites. As a result, I’ve seen quite a few posts asking about fundamental concepts, which is great because it shows that new networkers are getting out there and learning new things proactively.
