Since today, the RPKI Validation is running in our network. Invalid routes are strictly filtered by us. Thus, we now ensure with another mechanism that our network is also robust against (intentional) attacks based on false IP announcements (BGP announcements).We encourage every customer to sign their prefixes as well. For this, it is only necessary to create a ROA (Route Object Authorization) for the relevant prefix in its registry (Europe: RIPE).
