'IPv6 not supported for this device' when 'disable-ipv6: yes'

RouterOS Virtualization
1

I use RouterOS 7.1.1 CHR currently, and a lte on passthrough mode;

/ipv6/settings/set disable-ipv6=yes
/system/reboot

when rebooted

/interface/lte/disable lte1

Then print ‘failure: IPv6 not supported for this device’

Is that correct?

Actually, yes, because the “disable-ipv6=yes”. This configuration disables IPv6 per device so “IPv6 not supported for this device”.
