Network engineering analysis of one of the most unorthodox networking solutions for containers
Network engineering analysis of one of the most unorthodox networking solutions for containers
Exploring the problem of and solution to the random interface attachment order inside multi-network Docker containers
In this post I’ll show how to build a dockerized OpenStack and OpenContrail lab, integrate it with Juniper MX80 DC-GW and demonstrate one of Contrail’s most interesting and unique features called BGP-as-a-Service
In this post I’ll demonstrate how to build a simple OpenStack lab with OpenDaylight-managed virtual networking and integrate it with a Cisco IOS-XE data centre gateway using EVPN
In this post I’ll have a brief look at the NFV MANO framework developed by ETSI and create a simple vIDS network service using Tacker
In this post I’ll show how to configure Neutron’s service function chaining, troubleshoot it with Skydive and how SFC is implemented in OVS forwarding pipeline
I’m returning to my OpenStack SDN series to explore some of the new platform features like service function chaining, network service orchestration, intent-based networking and dynamic WAN routing. To kick things off I’m going to demonstrate my new fully-containerized OpenStack Lab that I’ve built using an OpenStack project called Kolla
A short post about how I do SSH session management for network devices in Linux
In this post I will show how to use IETF, OpenConfig and vendor-specific YANG models in Ansible to configure BGP peering and verify state of physical interfaces between IOS-XE and JUNOS devices.
One thing that puts a lot of network engineers off NETCONF and YANG is the complexity of the device configuration process. Even the simplest change involves multiple tools and requires some knowledge of XML. In this post I will show how to use simple, human-readable YAML configuration files to instantiate YANG models and push them down to network devices using a single command
