Nokia (Alcatel-Lucent) BGP configuration tutorial. Part 1 – basic eBGP, iBGP


When we say Service Provider, we imply BGP and when we say BGP, we imply Service Provider. There is no way I would leave you without covering configuration steps for one of the most versatile, scalable and robust internet protocols also known as BGP. And here it is – BGP configuration guide for Alcatel-Lucent Service Routers. As with OSPF configuration tutorial I will cover configuration process for various BGP scenarios along with verification and troubleshooting steps bundled with colorful figures, detailed code snippets and useful remarks.

BGP is so huge that I had no option but to write about it in several parts:

Part 1 dedicated to basic eBGP/iBGP configuration. We will practice with common BGP configuration procedures at first, then learn how to export routes into BGP process and prevent unnecessary route reflection by means of split-horizon over eBGP links. After that we will see how to configure iBGP to spread eBGP learned routes across Autonomous Systems. I will cover the necessity of full-mesh iBGP topology and the use of the  next-hop-self  command for iBGP peers.

It’s perfect time to configure some BGP, right?


How to achieve Alcatel-Lucent’s Network Routing Specialist I (NRS I) certification


Almost every networks-oriented vendor has its own certification program. Some of them are familiar to every network engineer (like Cisco or Juniper certification programs) other are less popular (say Huawei or Brocade certification). And if you are reading this post, then you know (or at least wanna to know) about Alcatel-Lucent’s Service Routing Certification (SRC) program.

In this post I will talk about the very first Alcatel-Lucent Service Routing CertificationNetwork Routing Specialist I (NRS I) and its corresponding exam Alcatel-Lucent Scalable IP Networks #4A0-100. I will shortly describe what is NRS I course about,  and will mostly talk about what the #4A0-100 exam: what Alcatel-Lucent-specific topics you should focus on and what preparation materials to use?

Fasten your seatbelt, newcomer, you’re gonna achieve another certification soon!
