Provider Centurylink. They have following configuration: <pre>Connection Type: Tunnel 6rd DHCP Option: Disable IPv6 Prefix: 2602:: IPv6 Prefix Length: 24 IPv4 Border Router: 205.171.2.64 IPv4 Router Mask Length: 0 Tunnel MTU: 0 Tunnel TTL: 255 As far as I understood to use it in systemd-networkd I need to create netdev with tunnel type sit and IPv6RapidDeploymentPrefix=2602::/24. I assume that it will configure sit tunnel with /56 prefix. May I use DHCPPrefixDelegation for that? Or it need to be configured some other way? Thanks, Vitalii Aksonov </pre> </body> </html>
