## Torino
Torino is the WAN router of the lab. On the external interface torino acts as a DHCPv6 client in order to receive a Prefix Delegation from the DSL-Router (Fritz!Box in this case). On the internal interface torino will serve Router Advertisements which is necessary for SLAAC. The hosts in the lab environment connectetd to the vSwitch will receive a prefix via SLAAC this way.
