The last days i spent several hours to try Bird2 as FlowSpec Controller and hopefully the post helps others to avoid some of my challenges.

First what means Client/Controller in an FlowSpec environment?

• A FlowSpec Controller is able to create FlowSpec Rules and Actions and announce them via BGP …

For a better understanding here are the picture of my iBGP Mesh:

First i had ipsec/gre for interconnecting my nodes itself, but now i completely switched to WireGuard. As it is really simple to setup (if you can compile an kernel module or use dkms), it is fast, high throughput and you don't need gre as with ipsec to use for …

Currently we had the following LAB generated:

• OVN-Central up & running
• kvmhost01 & 03 are connected as Chassis to OVN-Central
• Created an Logical Switch SERVER on OVN-Central

Before we go and create some VMs, we should discuss, how we want to interconnect them with the outside world. There are two major options …

I had some time and thoughts, how my internal Virtualized Network can be changed from libvirt, kvm, ovs, vlan based to something more "state of the art" but …

I setup a little network within DN42 to experiment and learn on BGP based networking. Currently my DN42 Network consists of 6 Nodes and more than 65 Peering ASN.

Within this Series of Articles i want to explain, what i do in my network and how it works.
