Brume 2 IPV6 via DHCP on WAN interface

Hi,

My parents ISP Gigaclear is rolling out actual IPv6 harmoniously with their CGNAT IPv4 deployment, due to complete end of April 2025.

The IPv6 is a /64 advertisement over DHCP, do I have to do anything for the Brume 2 to pick this up, or should it just automatically pick it up via DHCP request?

ip addr shows:


2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
    link/ether 94:83:c4:xx:xx:xx brd ff:ff:ff:ff:ff:ff
    inet 100.72.205.180/18 brd 100.72.255.255 scope global eth0
       valid_lft forever preferred_lft forever
    inet6 fe80::xxxx:xxxx:xxxx:xxxx/64 scope link
       valid_lft forever preferred_lft forever

Now that inet6 address is wrong, as fe80 is used for local ipv6 only, but the /64 prefix is correct, so as this is a simple IPoE connection assigned by DHCP via the ISP's radius, is the MT2500 ignoring the correct /64 IPv6 address?

Hello,

What the mode IPv6 uses? NAT6?

If a PC is directly connected to an ISP modem, will the PC obtain an IPv6 global address?
