Become a Paid Subscriber: https://podcasters.spotify.com/pod/show/darrell-davis99/subscribe Darrell Davis: Black and Green seeks to draw on my experience growing up in the Civil Rights/Human Rights movement. Using that experience, we hope to move toward real progress for Black people. We will explore bridging the often two separate strategies of protest and economic development. We will draw on the movements of the sixties to help guide us today. BLM, the exploitation of Black voters by the ...

I have removed myself from the political division, poison, and cyberbullying on Facebook. I have returned to my political roots: Self-Reliance! I will waste no more energy "debating" people who tell me to support a party that doesn't help me or my community—the Democrats. Self-Reliance is the other road to freedom. I am now firmly back on it!…

The linked video demonstrates RIPng, our first dynamic routing protocol for IPv6. This is a simple but inefficient routing protocol. The metric is based on number of router hops, with no provision for differentiating between links with drastically different bandwidth (a frame-relay hop has the same cost as a 10-gig-ethernet in RIPng). Each router m…

In 2003, I made a VOIP call from home while downloading a large email attachment. The DSL line saturated and my audio quality became horrible while VOIP packets (and email packets) were being dropped. Doubling the bandwidth to my home would not have solved this problem. The email download would simply have been faster, but the VOIP call would still…

The linked video introduces IPv6 theory. IPv6 is the 128-bit address replacement for IPv4. The Internet is expected to run out of it's 4-billion IPv4 addresses in 2012. IPv6 will replace IPv4 at the network-layer of the OSI stack. By replacing one layer in the stack, most applications and most layer-2 network devices will continue to function. IPv6…

The linked video provides guidance for optimal IOS version selection. The large number of IOS versions makes choosing the best version for your router or switch difficult. You must pick the most reliable version which includes the features you need. Different IOS "packages" have different features. For example, the "LAN base" package includes basic…

IOS routers can act as DHCP clients and DHCP servers. They can also function as Network Address Translation (NAT) devices. In this video we show a demonstration using a 2621 as a DHCP client, server, and NAT translation device for my home network. It's important to understand that most IOS routers have relatively slow CPU's. An IOS router is fine a…

In this episode we show a video demonstration of the hot standby router protocol. This is a Cisco proprietary redundancy protocol. The purpose is to allow two routers to share one virtual IP address on an access subnet/vlan. Hosts on the subnet can use the virtual IP for their default route. This way if one router goes down the redundant router wil…

This video demonstrates layer-2 convergence in less than 2 seconds thanks to rapid spanning-tree. Rapid per-vlan spanning-tree is configured with "spanning-tree mode rapid-pvst". The rapid spanning tree protocol, 802.1w, is the answer to the slow convergence time of the historic 802.1d spanning-tree protocol. Rapid spanning tree replaces timers wit…

When you have two different links between the same two switches, normally spanning tree will forward on one and block on the other. This means half of your bandwidth is sitting idle. An etherchannel is a way to bind two links into one logical link with twice the bandwidth. In addition to increased bandwidth, etherchannels fail over in a fraction of…
