Collection of useful, relevant or just fun places on the Internets for 20th July 2013 and a bit commentary about what I’ve found interesting about them:
MOSX Tumblelog – Andreas is releasing tip son uses for MindNode mind map tool. This is one that I use regularly when writing:
You can use MindNode as an OPML generator. OPML can be used by many writing apps to generate a basic bare-bones structure for a document.
VIRL – Why you need to know about it! | kemot-net.com – Another post on VIRL :
Below is a screen shot of VIRL. It is using Oracles VMMaestro GUI based on Java. In the screen you can see network topology which is drop and drag. On the left side in purple there is a list of all saved networks. The right middle side has a list of supported devices. Top right side has all of the currently running devices and bottom right preconfiguration tabs. To access CLI of these routers, you has to run in simulation mode then Telnet to individual devices. The preconfiguration is a nice feature that allows you preconfigure IP addresses, Loopback interfaces or routing protocols like OSPF or BGP.
VIRL Saves the Day! – Nathan Sowatsky from Cisco talks about VIRL
VIRL is a network simulation system based on OpenStack and virtual instances of our core network operating systems (NOSs). With the VMMaestro GUI, one can create, with drag-and-drop, network topologies, and have the configuration auto-generated. Then, with a single click, one starts the simulation engine. The network topology is realised as a running network of VMs, each of which is an instance of a Cisco NOS representing a switch or routing platform, orchestrated by OpenStack.
Going VIRL | Herding Packets – Bob McCouch gets very excited about VIRL and rightly so.
This year’s Cisco Live saw a number of interesting product announcements, but one that made a lot of buzz among serious geeks was VIRL. In a nutshell, it’s a software-based lab environment which can run a number of Cisco routing and switching platforms. Think GNS3, but official, without licensing concerns, and capable of running current-generation software. VIRL actually goes far beyond what GNS3 is capable of, as I describe in this article.
Long overdue but seems to be a comprehensive response to what customers have been asking for more than five years.
