IPv6 in my LAN with Unitymedia, Technicolor TC7200, Ubiquiti EdgeOS on Edgerouter X and Prefix Delegation
This post describes how to set up IPv6 with Edgerouter X (and supposedly any EdgeOS device) in interplay with the infameous Technicolor TC7200 cable modem as provided by Unitymedia in Germany, using prefix delegation to advertise valid IPv6 addresses into the LAN. This guide shows how to configure settings via GUI instead of CLI.
