+The following configuration will setup a PPPoE session source from eth1 and
+assign a /64 prefix out of a /56 delegation (requested from the ISP) to eth0.
+The IPv6 address assigned to eth0 will be <prefix>::1/64. If you do not know
+the prefix size delegated to you, start with sla-len 0.
+
+In addition we setup IPv6 :abbr:`RA (Router Advertisements)` to make the
+prefix known on the eth0 link.
