I’ve got a route 10 in my lab. Currently testing it on a DHCP connection (vlan 10 tag on wan) with IPv4 DHCP + IPv6-ND with PD. BNG is Juniper MX480, other CPE’s get an ipv6 address and a delegation just fine… but not the route 10.
Also there doesnt appear to be any display for IPv6 addresses like there is IPv4.
Edit: Sorry for the silly question, as I realized that your description implies that the IPv6 is enabled. Anyhow, did you check the pop-up for the Route10 on the Network devices page? I believe your screenshot shows the gateway device connected to the WAN port rather than info on the Route10.
