How to determine the router address received on IPv6 WAN/ISP port when add-default-route=false in /ipv6/dhcp-client ?
With (relatively recent) ROS v7, it should be shown in output of /ipv6/address/print. In v6 (and early v7?) all the info, received by DHCPv6 and RAs, is indeed hidden.
The IPv6 gateway(next hop) address received from RA on ether2 is fe80::aada:cff:feff:8476
In my opnion it does not reflect the the same. Find the attached screenshots of the same.
Thanks.

It’s completely normal to see link-local addresses (fe80:
as next-hop addresses, in fact ROS advertises its link-local address in RAs. And it’s completely fine for router not to have GUA on its WAN interface … and DHCPv6 client only requests it if it’s configured to do so (most of time requesting a prefix is enough).
When router itself needs to communicate beyond its upstream peer, it’ll use one of LAN GUAs (if it doesn’t have a WAN GUA). Which again is completely fine.
