I use ASUS router for dialing. According to the log information, the ISP seems to assign a prefix of /60, but the prefix of router and ppp0 is /64. I made some attempts but could not configure a shorter prefix.

Code:
dhcp6_client: WAN Prefix Size Requested:/60, Received:/60
dhcp6_client: bound prefix xxx::/64

There is no problem.
Your ISP assigned a WAN prefix of /60, giving you 16 /64 LAN prefixes for your own use, to subnet your LANs (give vlans their own IPv6 subnet?).

What are you talking about? The router uses a /64 prefix, which makes it impossible to use SLAAC to segment the IPv6 network segment.
