More: Hardware Differences between Routers and Switches
Aaron Glenn sent me his thoughts on hardware differences between routers and switches based on the last paragraph of Dmytro Shypovalov’s views on the topic
To conclude, what is the difference between routers and switches in my opinion? I have absolutely no idea.

We’re introducing new capabilities to help our customers prepare for upgrading to the latest releases — now available with NSX-T Data Center 3.2.0.1.
To ensure that existing NSX deployments can be successfully upgraded to NSX-T Data Center 3.2.x, we have provided an NSX Upgrade Evaluation Tool that operates non-intrusively as a separate downloadable tool to check the health and readiness of your NSX Managers prior to upgrade. Using NSX Upgrade Evaluation Tool can help avoid potential upgrade failures and save time by avoiding a rollback from a failed upgrade.
Customers upgrading to NSX-T 3.2.x are strongly encouraged to review the Upgrade Checklist and run the NSX Upgrade Evaluation Tool before starting the upgrade process.
In what follows, we’ll go over the details of the NSX Upgrade Evaluation Tool:
- How the tool works
- When to use the tool
- What the tool can and cannot do
- How to use the tool
How the NSX Upgrade Evaluation Tool Works
The main component of the NSX Upgrade Evaluation Tool is the database where a copy of NSX objects will be stored. The tool starts by making a secure copy of the database from an existing NSX Manager Continue reading
Burkina Faso experiencing second major Internet disruption this year
The early hours of Sunday, January 23, 2022, started in Burkina Faso with an Internet outage or shutdown. Heavy gunfire in an army mutiny could be related to the outage according to the New York Times (“mobile Internet services were shut down”). As of today, there are three countries affected by major Internet disruptions — Tonga and Yemen are the others.
Cloudflare Radar shows that Internet traffic dropped significantly in the West African country after ~09:15 UTC (the same in local time) and remains low more than 24 hours later. Burkina Faso also had a mobile Internet shutdown on January 10, 2022, and another we reported in late November 2021.
The main ISPs from Burkina Faso were affected. The two leading Internet Service Providers Orange and FasoNet lost Internet traffic after 09:15 UTC, but also Telecel Faso, as the next chart shows. This morning, at around 10:00 UTC there was some traffic from FasoNet but less than half of what we saw at the same time in preceding days.
It’s not only mobile traffic that is affected. Desktop traffic is also impacted. In Burkina Faso, our data shows that mobile devices normally represent 70% of Internet traffic.
With the Burkina Continue reading
Sample Lab: RSVP TE on Junos
It’s amazing how creative networking engineers become once they have the basic tools to get the job done a bit quicker. Last week Pete Crocker published the largest topology I’ve seen built with netsim-tools so far: a 13-router lab running RSVP TE to transport IP traffic between external autonomous systems1.

Junos Part I – the basics
In this post, we take an introductory look at the operating system used in Juniper platforms, called Junos OS. This post serves as an introduction to the CLI. We also cover basic bridging.
Automation 10. Installing NAPALM Community Driver for Nokia SRO OS and comparing NAPALM and OpenConfig/YANG.
Hello my friend,
In the previous blogpost we have compared the usage of NAPALM and OpenConfig YANG modules with NETCONF transport for Cisco IOS XR and Arista EOS. Those two operation systems are so called core operating systems for NAPALM and are included in its standard distribution. Besides them, other three (there are five core network operating systems in NAPALM) are Cisco IOS, Cisco Nexus, and Juniper Junos. You though can use NAPALM with other operating systems, if there are community drivers available. In today’s blogpost we cover installation and usage of NAPALM Community Driver for Nokia SR OS and its comparison against OpenConfig/YANG with NETCONF.
