SP. Part 1. Segment-Routing and IP-VPN for with Arista, Cisco, Nokia

Hello my friend,

Two years ago we’ve discussed how to configure Segment Routing between Nokia (Alcatel-Lucent) SR OS and Cisco IOS XR. Both of these vendors are well-known in Service Provider industry as they are delivering networks in this filed for a long time. But the world isn’t stable and nobody knows what will happen tomorrow. And traditional data centre vendors start looking to SP WAN.

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

Hello my friend,

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,

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.

Model-driven command line interface (MD-CLI) in Nokia SR OS 16.0

Hello my friend,

Today topic of the network programmability is popular. There is a quite pragmatic approach behind this popularity, which is to lower the operational costs of the network and increase its agility. By agility I mean the way how we create the network services, which time we spend on it and so on. Let’s evaluate how model-driven configuration can help us to do it for Nokia SR OS 16.0.
