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
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
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 ?
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.
I thought this was a nice MPLS-TP intro from Ciena – not too much detail, and a bit oddly produced, but good all the same:
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 […]

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.
This post represents the solution and explanation for quiz-7. The junior network administrator tried to update the configuration on a switch by enabling mls qos
and immediatelly created an outage. See what happened !
Introduction In my previous post, I proposed investing in careful planning to extract the maximum value from your vendor meeting. But what happens when the presentation begins? In this post, I’ll outline a few high-level questions and lots of in-depth questions to help you get a better understanding of the ‘real’ product that’s being sold. High-level […]

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 […]
EIGRP Offset-list is usually used to increase the metric of routes being advertised over a link, but can it be used to filter EIGRP prefixes?
I thought about using offset-list in RIP to filter specific routes and thought how about doing the same thing in EIGRP? I haven’t run into any examples or blog posts of using Offset-list in EIGRP to filter routes so I thought about labing it out to see if that’s possible.
To test it, I went to the handy GNS3 with the following topology.
Three routes R1, R2 and R3. R1 advertises a Loopback0 subnet 10.1.1.1/32 which I will use to test filtering using offset-list. As you can see in the diagram, I changed the Delay for each interface to 1 just to make things easier for metric calculation (including loop0 interface). I also set the EIGRP metric weight to only consider delay and not to look at bandwidth for metric calculation, again to make things easier.
My goal is to set an offset-list on R2 to filter routes to R3 using Delay and offset-list commands only. Theoretically, if I know the max metric of EIGRP routes and I apply an offset-list with Continue reading
“…I’d love to share how certifications have propelled me into a mid-level networking position. I can share my own personality, thoughts, and views on the subject… as long as I’m doing self-study. I don’t like having a teacher and same goes with a job, I personally really enjoy being my own technical lead, which I […]

This past January, Anuta Networks came out of stealth at Cisco Live in London, showing off their nCloudX platform, an SDN controller aimed at multitenant cloud providers. Anuta’s nCloudX controller can manage hardware common to many networks. As such, Anuta isn’t forcing providers to install OpenFlow switches, build a tunnel fabric, or otherwise disrupt their production environments […]
