[IPv6] How 6to4 works : from your 2002::/16 LAN to the IPv6 Internet

Last article about 6to4 explained how your 6to4, ie 2002::16 network is reached from the IPv6 internet. Good news is that it was the hardest part to explain and understand. Still, the question remains : when youdecide to send packets to the IPv6 Internet through the IPv4 Internet with 6to4,

[IPv6] How 6to4 works : from IPv6 Internet to your 2002::/16 LAN

6to4 is one mechanism used for the transition of IPv4 to IPv6, precisely to route packets to an IPv6 network through an IPv4 network. Let’s see how the IPv6 Internet knows how to route packets to your LAN with 6to4. [/content/images/wordpress/2012/11/Problem3.png]Your IPv6

RIP timers and reality, #3 (HOLDDOWN again)

We’re now going to test a different topology introduced at the end of article #2. We are now going to test the HOLDDOWN timer of RIP when the backup router send a route with a metric higher than the primary router. In this series of tests, we’ll see

RIP timers and reality, #2 (HOLDDOWN)

Let’s continue our discovery of the RIP timers in a slightly different topology, and discover the odd Holddown timer. Second configuration [https://bibelo.info/content/images/wordpress/2012/09/Blog-article-Config2.png] Normal situation: R101 advertises R100 for NETWORK with a RIP metric of 1. R100 has one route for

RIP timers and reality, #1 (INVALID and FLUSH)

Short article about what really happens with RIP timers. I’ve run some tests putting in situation network advertisements for downlinks and how and when timers react. The different tests are given in the form of timelines, with the action and reaction at the minute planned. Between brackets you’ll
