My Tools for Studying

Anyway, I thought it would be neat to document the tools I'm using today. It'll be interesting to read this in a couple of years to see how things have changed again and maybe it'll give a fellow cert-chaser some ideas for today.

A Contest of Protocols: EIGRP or OSPF?

Ah, the age old question that nearly every CCNA and CCNP candidate asks of themselves and others at some point. We see a minimum of 4 routing protocols in our networking studies, more if you decide to take on the Service Provider track. What makes one routing protocol better than another? I think it’s clear why (at least mostly) these particular two protocols are different, keeping in mind that one is distance vector (yes, distance vector, not hybrid distance vector) and the other is link state.

Packet Design’s Route Explorer Integrated with Juniper Networks Junosphere Lab

SANTA CLARA, Calif., October 4, 2011 – Packet Design has integrated its Route Explorer route analytics solution with the Juniper Networks® Junosphere™ Lab cloud-based service, giving Juniper customers a way to visualize and analyze complex Layer 3 routed networks created in the Junosphere virtual environment.

Route Explorer provides real-time, network-wide Layer 3 visibility across an enterprise or service provider's IP/MPLS/VPN network, delivering an intuitive graphical view of control plane operation, including IP forwarding paths, RSVP-TE tunnels and Layer 3 VPN services. Integration with Junosphere will allow users to see a real-time topology map of their virtual network, monitor routing changes, perform in-depth analyses, including the ability to rewind network event history, and graphically depict what-if scenarios for failure analysis or to understand the impact of changes before they are deployed. Route Explorer functionality is provided free of charge to Junosphere Lab users.

Judy Beningson, vice president and general manager, Virtual Junos Business Unit at Juniper Networks , said, “We are excited to expand our partnership with Packet Design, and to bring Route Explorer’s powerful network visualization and analysis capabilities to Junosphere Lab users. Route Explorer will give users of our ground-breaking cloud-based service additional flexibility, allowing our customers to Continue reading

Broadview Networks Deploys Packet Design’s VPN Explorer to Manage Converged Services Network

IP Routing and MPLS VPN Visibility Increases Network Operations Efficiency, Reduces Mean-Time-to-Repair

SANTA CLARA, Calif., December 20, 2010 – Broadview Networks, a business communications service provider, has deployed VPN Explorer, an IP/MPLS VPN routing analysis solution from Packet Design, Inc. Broadview will use VPN Explorer to manage their IP network, which provides business customers with VoIP, Internet, VPN and MPLS-enabled data communications.

Broadview Networks installed VPN Explorer earlier this year to monitor its large router network, which runs the Open Shortest Path First (OSPF), Border Gateway Protocol (BGP) and Multi-Protocol BGP (MP-BGP) MPLS VPN routing protocols. VPN Explorer uses a technology known as ‘route analytics’ that lets the company's network engineering staff look at otherwise hidden aspects of routing behavior – undetectable by conventional SNMP-based management tools – and understand its impact on network reliability, redundancy, and customer service delivery.

George Carey, managing director of ISP Operations for Broadview Networks, said the need for more visibility into IP and MPLS VPN routing has increased with the growth of Broadview’s service portfolio and the expansion of the network. “Our IP backbone network has grown to support many diverse services, including more than 50,000 OfficeSuite™ hosted IP phone stations, SIP trunking, Continue reading

Quiz #10 &#8211 OSPF on CE-PE links

Company ABC has multiple offices interconnected via an MPLS provider and each office runs OSPF with a separate Area number.
In one of the offices, there is an internal router that uses VRFs. You notice that some routes are not learned. Why ?

Show 140 – Introduction OpenStack and Quantum Projects

OpenStack is progressively developing into a product that networking needs to be a part of. One way to describe OpenStack is to say it’s an API for infrastructure. OpenStack is a combination of open source plus a significant number of hardware vendors who see contributions to OpenStack as a way of growing or maintaining their own markets and customers.

Customers want OpenStack as an alternative to VMware or other commercial software - not all applications and service need to have expensive software licenses and maintenance. We need to be able to build a core of functional services that can deliver services.

In the future, it seems likely that OpenStack Quantum API will be important. We discuss Open Vswitch and how it’s changing from being a “switch” to including routing, firewall and load balancing features. If you don’t like that, you could consider using Quantum API as a way to consume load balancers from your preferred vendor - the API exists to simplify the consumption of network resources.

Nexus 5000 QoS – Keeping It Classless Labs

I’m pleased to revive the KIC LABS series with a video on Cisco MQC-style QoS on the Nexus 5000. PLEASE read these two articles first, as they do a lot better job at explaining the structure that we’re going to be putting together in the video. Unfortunately I was not able to provide this during the video, as I was pressed for time. https://keepingitclassless.net/2012/11/cisco-quality-of-service-part-1-types-of-qos-policies/ https://keepingitclassless.net/2012/11/qos-part-2-qos-and-jumbo-frames-on-nexus-ucs-and-vmware/ Download the configuration used in this video here.

What’s Next for OpenFlow and Open Source?

One year ago, the Open Networking Foundation was setting a blistering pace of standards development. Though their process is closed to outsiders, word had leaked out that not only were they on track to produce version 1.3 of the OpenFlow standard, but 1.4 would follow before the end of 2012. At some point that plan […]

What’s that % sign after ipconfig IPv6 address?

How does the internet work - We know what is networking

I see a % ## in my IPv6 address… what is it?? Because all Link-Local Addresses share the same network identifier (fe80::), you cannot determine which interface an LLA is bound to merely by looking at the address. Therefore, if a computer running Windows has multiple network adapters connected to different network segments, it distinguishes the networks by using a numeric zone ID following a percent sign after the IP address.

What’s that % sign after ipconfig IPv6 address?

Cisco Exams

This started off as a company email but I wanted to share it, since I’ve been asked before. Below is opinion and opinion only. I’m more interested in how this compares with your study methods and Cisco exam experiences, so please let me know your thoughts in the comments. Cisco exams….let’s face it, they suck. (In a good way though) I’ve taken exams from all kinds of vendors, and Cisco is really good at creating exams that vet you technically, but also require that you understand the practical reasons for the technologies we work with, not just memorizing maximum values, or configuration steps.

RADIUS server Infrastructure

How does the internet work - We know what is networking

In short RADIUS means Remote Authentication Dial-In User Service server or proxy.  This is the best technology and as far as I know the only technology for all centralized accounting and authorization for connecting to networks. It is a standard. This technology will help you control who will be able to connect to your network and who will not […]
