This article is the 5th part of my dn42 experiment. The objective is to monitor, graph and visualize the network flows in a network weathermap using LibreNMS.

This article is the 4th part of my dn42 experiment, it describes the configuration of a primary and secondary DNS servers, using bind under Debian 12.

This article is the 3rd part of my dn42 experiment, it describes the configuration of a second router (“multi-pop”) and the addition of more BGP peering links (“multi-homing”), using an internal peering link between both routers.

This article is the 2nd part of my dn42 experiment and will present all my configuration notes from the initial set-up of my first router server to my first peering session on dn42.

dn42 is a decentralized network, which employs Internet technologies (such as BGP). It is an ideal testbed to manipulate networking technologies without the pressure of running a public AS. This article is the start of my journey to dn42, from the request of my AS number and IP ranges to the monitoring of my peering links.
