BGP did bite me in the ass

After setting up and learning Cilium, I got myself in quite a way. Before installation, you need to properly map out which addresses you want to use.
My first results , and they were difficult to change afterwards, was that Cilium started advertising my home network at least by default with me. As a result, when
Cilium started on the cluster because of the bgp advertisements for the data centre, it could no longer reach my home network. Learnt something again, and something that in my default installation
process gets tackled.
