One year on air

Hello my friend,

A year ago, on 5. June 2016 I’ve posted my first article about joint operation about Nokia (Alcatel-Lucent) SR OS and Cisco IOS XR with explanation how to connect two virtual routers on your laptop. Since then 33 articles were posted. Let’s make a quick recap what we have discussed so far.

Candidate config in Nokia (Alcatel-Lucent) SR and Cisco IOS XR

Hello my friend,

I’ll step aside for a moment from discussing the configuration of the technologies in Nokia (Alcatel-Lucent) SR OS and Cisco IOS XR and will talk about the process of configuration itself. Recently my colleague Greg Hankins has posted information about candidate config in Nokia (Alcatel-Lucent) SR OS. I want to show you how this feature works and outline one interesting fact about it.

Configuring OSPF between Nokia (Alcatel-Lucent) SR OS and Cisco IOS XR

Hello my friend,
This article will be quite long so make a cup of tea for you sit more comfortable. Though the configuration of any routing protocol (IGP) can be relatively quick and short, usually you have to tune many additional parameters to get desired level of speed and reliability. I won’t cover all the features of OSPF, as it’s just impossible, but I will provide more or less complete config, which is used in service provider network.

Trunking in virtual world (Nokia (Alcatel-Lucent) SR OS, Cisco IOS XR, Linux)

Hello my friend,

In this article I’ll step aside from traditional approach, where I describe configuration only of Cisco IOS XR and Nokia (Alcatel-Lucent) SR OS. As we have fully virtual lab, we have to take into consideration how VLANs are trunked in Linux. It’s crucial not only for our lab, but also for SDN environment, where different NFVs are connected using VLANs and pass through the production traffic (i.E. from VLAN X to VLAN Y).

What does service provider router consist of (Nokia (Alcatel-Lucent) and Cisco)?

Hello my friend,

This article isn’t the same as I’ve written previously. I won’t provide the configuration of routers comparing syntax at Cisco IOS XR and Nokia (Alcatel-Lucent) SR OS. Instead I’ll review the hardware architecture of service provider routers and how mentioned vendors call their parts. As you can imagine their architectures are the same.

Logging and debugging in Nokia (Alcatel-Lucent) SR OS and Cisco IOS XR

Hello my friend,

Logs are one of the most valuable (and therefore important) things, which we have in troubleshooting of our network devices and services. The brief overview of logs gives us understanding of what and when has happened. This paradigm is applicable both for production and lab environment, that’s why we proceed further with configuration of logging at Nokia (Alcatel-Lucent) SR OS and Cisco IOS XR.

Connecting Nokia (Alcatel-Lucent) VSR to Cisco IOS XRv at your laptop

Hello my friend,

In this article I’ll show you how to establish basic virtual network between Alcatel-Lucent (or already Nokia) virtualized service router (VSR) and Cisco IOS XR virtual (IOS XRv). Such installation has three main goals:

  • Test interoperability of certain features between popular and respectable vendors before deployment
  • Develop best practices design in case of multivendor network
  • Learning and education

If you are excited about these ideas how I do, I welcome you to read this article till the end.

How to send MPLS labels?

Dear friend,
A couple of years ago I thought that MPLS is almost identical to LDP meaning that labels must be distributes by this protocols. I knew that there was BGP as well, but its solely task, which was related to MPLS, was to distribute VPN routes and labels. Now I understand, how far from reality I was. That’s why I want to share with you solid structure, what MPLS label is and how it can be distributed.

Insights from PMBOK

Hello my friend,

I suppose you have heard such abbreviations as PMBOK and PMI, if you are interested in project management. Let’s discuss, what are they are, and try to outline, how they can help you. Myself I’ve just finished studying PMBOK and want to share with you my own opinion.
