OSPF Path Cost Consistency
What does OSPF do for me? Open Shortest Path First (OSPF) is a standards-based routing protocol for IPv4. It is used to advertise paths to a network prefix between routers. As a router receives advertisements for prefixes, so it creates a representation of the network…
Using IP Fabric with Nornir
Today we have some great news for Nornir users – a plugin for IP Fabric has just been released, allowing use of IP Fabric network inventory for Nornir automation! And as we understand that seeing is believing, we have prepared a free 1 month trial…
Verify end-to-end QoS
Verifying Quality of Service is a complex task when delivering applications across a large network. It involves a detailed understanding of the behaviour of many different devices, often from different vendors. This post shows how IP Fabric can help with this onerous task. Quality of…
Cisco Meraki discovery and visibility
The Cisco Meraki is a unique network equipment vendor that decided to move all management related functions to the cloud. It may sound not completely secure or unusual to some, but in 2020 the market seems ready for that. With Cisco Meraki, you can build…
Spotting Single Points of Failure
Design for availability The fundamental purpose of a data network is to connect users with applications, data producers and consumers with storage. The most desirable feature of a network is to maximise availability of those services to the endpoints that consume them. In order to…
End to end path simulation with IP Fabric’s API
The ability to perform end to end path simulation quickly across complex network environments means fast response to any issues or current design process requirements. The main reason that computer networks are built is to enable communication between two or more endpoints and the whole…
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…
