After looking https://wiki.openwrt.org/doc/uci/network6#downstream_configuration_for_lan-interfaces I tried to make couple changes to my /etc/config/network file to look like this Maybe OpenWRT will fallback to a different prefix length but I'm also not sure about this one. For prefix delegation to work downstream, there should be several /64 prefixes available (at least two, so that the Openwrt router would keep one for itself and its WAN side (=modem side) and assign the other for its LAN). I did not set anything up myself in this regard. Maybe there is a problem with netifd/ubus (or something else) where the reporting/handling of prefix delegation is bugged. and launches the ppp daemon with the mtu specified.

Most home routers have 4 LAN ports, so that a /56 will be divided into /60s to be allocated to the first tier of routers (Router A, Router B, Router C). So I rebooted the device. This example requests a /56 sized prefix and DNS servers on wan and configures two /64 subnets out of the prefix on lan and loopback. I'm not sure.

Does it work now? Prefix delegation OpenWRT - he the ppp daemon gets launched with mtu 1492, Does this mean that the configuration should reference the dynamically created "wan_6" interface as opposed to "wan6" shown above?
