Recently Iíve come across some interesting terms for variants of common network topologies, so I decided I’d try to list as many of them as I can for reference. Please suggest others to add.
Please welcome Ziyad Basheer for his first post on EtherealMind.
Network automation tools are nothing new, but vendors are starting to implement deployment simplifying tools such as Cisco’s AutoQoS and AutoSecure. These tools for reducing repetitive deployments’ costs and assist configuration are a mark of a trend. Dynamic deployment tools will only get more popular and eventually gain mainstream deployment within the multiple facets of the network.†
Following my article on Loop-Free Alternate Routes, Michael McNamara made a good point about some of the issues detecting failure in a Metro Ethernet network. This seems to be a commonly misunderstood problem.
Whilst at Cisco Live recently I was intrigued to learn about an apparently simple yet effective fast routing convergence technique called Loop-Free Alternate Fast ReRoute (LFA-FRR), a.k.a. IP Fast ReRoute (IP-FRR).
Many service providers and enterprises these days tune their interior gateway protocol (IGP) timers, aiming to achieve sub-200ms convergence. This can be quite an intensive and design impacting challenge.
Of all the disciplines that are needed by a ëNetwork Consultantí, the one of design is by far the most difficult for me. For years I wondered why I found designing solutions difficult. I’m a CCIE with over 15 years experience; Iíve worked with some great networking people and on some very complex networks. Iíve got a stack of excellent books, Iíve even read some of them, yet I still find it difficult to be decisive and confident when designing.
