BGP resiliency and received prefixes
BGP is famously known for being the routing protocol of the internet, but not only. A lot of companies are using BGP in their internal network. One of the main reasons for that: it allows great control and flexibility with routing exchange. As with any…
Identifying BGP instability
There are many elements that contribute to the availability of services delivered across any network. Redundancy in the topology, coupled with resilience in the configuration are key. Routing protocols are used to manage that redundancy and failover to backup traffic paths should a failure occur…
IP Fabric adds View Builder and Firepower support among other improvements in milestone release 3.1.0
With a growing number of customers and requests, the initial plans for minor bugfix release have been expanded into a major release which improves upon nearly all aspects of the product. Here we’ll cover the biggest changes in the major release of IP Fabric 3.1.0….
Fresh new version 3.0.5 just released
Would you appreciate much faster end-to-end path lookup simulation on big networks, prettier diagram layout or more extensive routing protocol support? We thought so and that’s why we decided to create even more seamless experience through recent updates. Let’s summarize all the effort. Added protocol…
Unlocking new vendors
The latest 2.2.8 version released very recently again brought new powerful features and updates to our customers. IP Fabric is continuously gathering feedback and request from customers and one of them was to be able to work with more network devices and vendors, specifically devices…
Routing Protocol Visualization
Routing, one of the most important features in network world. It’s been at least a two decades since most of ISPs rely on Border Gateway Protocol (BGP) in their core, supported by Interior Gateway Protocols (IGP). Local area networks are running and routing with use…
Discovering First Hop Redundancy Protocol parameters
To begin with, IP network gateway redundancy has become a very standard high availability solution. In IP Fabric’s platform it’s described as First Hop Redundancy Protocol (FHRP) feature that currently umbrellas HSRP, VRRP and GLBP protocol. I have prepared a little scenario in our virtual…
Chasing routes in the network
Have you ever tried to find out why the dynamic routing protocol in your network is not passing specific prefix as expected? And the situation had not improved even though ad-hoc static routes were created here and there? Networking protocols are designed to be simple…
Evaluating network performance using loss and topology awareness
Monitoring loss in a specific flow or service is precise but has a number of inherent disadvantages, such as that it must be explicitly provisioned, that the resulting measurement only tells information about a single service path, and that there is no specific information of where the loss occurred or what caused it.
