Cheat sheet for automated creation of networking lab in KVM on Linux: Arista, Cisco, Cumulus, Nokia

Hello my friend,

Some time ago we have discussed how Ansible could be used as VNF manager for onboarding and deleting the VMs in Linux. I have got some feedbacks, that not everything is easy or could be reproduced, so I decided to find the easier way, how to help you with the creation of virtual labs to train your networking and programming skills (assuming you are using Ansible).

Two years on air

Hello my friend,

Two years, on 5. June 2016 I have posted the first article on the topic of interoperability between Nokia (Alcatel-Lucent) SR OS and Cisco IOS XR. That article shaped the main line for all my blogs, and this line is “interoperability”. But not only. In the first year we focused on Service providers IP Core and Backhaul technologies, whereas in the second year SDN, data centers and automations were in focus and also introduction of new vendors to our interops.

EVPN/VXLAN for Data Centre with Nokia (Alcatel-Lucent) SR OS and Arista EOS – Part 5

Hello my friend,

Probably you are already bored with data center stuff, but I’m writing about it again. The reason for that is very easy: it’s data center era now. With growth of cloud services and so on, we need to have more data centers, much more. That’s why I’m introducing interoperability between Nokia (Alcatel-Lucent) SR OS and new product in my lab, which is Arista EOS.

EVPN/VXLAN for Data Centre with Nokia (Alcatel-Lucent) SR OS and Cumulus Linux – Part 4

Hello my friend,

We have discussed so far EVPN with BGP signaling and VXLAN data plane with different scenarios: pure switching, inter-VXLAN routing and even BGP peering from VM to leaf. But all the leafs were Nokia (Alcatel-Lucent) SR OS, as Cisco IOS XRv doesn’t support VXLAN. In this article we’ll replace on leaf with Cumulus Linux VX, so let’s see how we achieve interoperability now.
