For those who have followed my in the last few years know that I am a big fan of Layer 3 routing, BGP, VXLAN and EVPN.

Recently, I became a RIPE member, which resulted in an IPv6 /29 subnet being allocated to me.

Early 2025 I’ve decided to become a RIPE member with my own holding (BV, Netherlands) so I could obtain my own ASN and IPv6 PA space.

Many Ceph storage environments out there are deployed using a L2 underlay.

Our house (2020) is being heated and cooled by a Stiebel Eltron WPL20AC heatpump.

Recently I was asked to assist with setting up a BGP+EVPN+VXLAN network where Juniper MX204 routers would be the gateways in the VNI and the rest of the network would consist of Spine and Leaf switches running Cumulus Linux.

I recently upgraded my Lenovo X1 Carbon (5th gen) from Ubuntu 20.04 to 22.04 and my 4G connection stopped working.

Proxmox by default does not support BGP+EVPN+VXLAN but there is a small piece of documentation on the Wiki of Proxmox.

Apache CloudStack does not have a build-in mechanism to rate-limit failed authentication attemps on the API.

When we talk about IP protocols and IPv6 in this particular case we think about routing over the internet.
