In an earlier blog, I have talked about Linux bridge based virtual networking. Recently as part of a comment on my blog, I learnt how to view and interpret the MAC table of Linux bridge. In this installment of WILT (What I Learnt Today) series, I will share how MAC Table can be used for troubleshooting Linux bridges.
Here I am once again, with fresh blogging and learning goals for the first half of 2015. This time I am able to share my goals earlier than usual. In the past, I was delayed by almost 2 months. This is clearly a good start for me and I hope that the rest of the year, I am able to stick to a better cadence for my blogging.
Neutron is the networking project within the OpenStack cloud platform. The purpose of OpenStack Neutron is to provide physical and virtual network resources to the instances (or virtual machines). Before you continue to read this article I would recommend that you read about OpenStack networking concepts. To appreciate the architecture and the functionality of Neutron, it is important to understand the components that are part of Neutron.
In the next installment of “What I learnt today” or WILT, I briefly touch upon Network Namespace. I came across Namespace as part of my ongoing study of OpenStack networking. Namespaces are powerful constructs in Linux that allows you to create a copy of the TCP/IP network stack -all the way from the Ethernet interfaces (L2), routing tables etc.
Here is my mid-year (I know I am off by couple of months) review of my blogging and learning goals for 2014. I will start off with my assessment of the first half of 2014 and then wrap with goals for the remaining four months of this year.
