Some ISPs (e.g. Comcast in Australia) only delegate a /64 by default. You have to explicitly ask for a /60 prefix (see discussion in T421).
Add CLI node to „help“ the dhcp client to request an appropriate size.

Guess the CLI needs a change here as this requirement was overseen. It could look something like this (note that PPPoE can be replaced by any other interface), need to work out the details.
+pppoe pppoe0 { + authentication { + password vyos + user vyos + } + dhcpv6-options { + prefix-delegation { + interface eth1 { + address 1 + sla-id 0 + sla-len 5 + } + length 60 + } + } + ipv6 { + address { + autoconf + } + enable + } + mtu 1400 + source-interface eth0.202 + vrf black +}
I‘m asking myself if length should be specified as decimal number or as ::/60 prefix?
