I met great difficulties to setup fios ipv6 on my 21.02.3 router, test-ipv6 failed and ping6 ipv6.google all packets lost
I changed wan6 section in /etc/config/network, and other settings are default
config interface 'wan6'
option device 'wan'
option proto 'dhcpv6'
option reqaddress 'try'
option reqprefix '56'
option norelease '1'
and status seems ok
