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).

OpenConfig. Part 3. Advanced OpenConfig (w/ Ansible) for Arista EOS, Cisco IOS XR and Nokia SR OS: route policy BGP and interfaces again

Hello my friend,

Today we’ll continue (and probably finalize) our conceptual discussion about OpenConfig for the automation of the data center network based on BGP-EVPN/VXLAN. We’ll speak about BGP and associated routing policies and again about interfaces, but we’ll do it from different angle comparing to the first OpenConfig article. So we won’t create the jinja2 templates ourselves, but we’ll rely on built in functionality in “pyang “tool instead.

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.
