My main route uses the following DHCPv6 server configuration:
```
set service dhcpv6-server preference '0'
set service dhcpv6-server shared-network-name pri101 subnet fc00:470:f1cd:101::/64 address-range prefix fc00:470:f1cd:101::/64 temporary
set service dhcpv6-server shared-network-name pri101 subnet fc00:470:f1cd:101::/64 address-range start fc00:470:f1cd:101::8 stop 'fc00:470:f1cd:101:ffff:ffff:ffff:ffff'
set service dhcpv6-server shared-network-name pri101 subnet fc00:470:f1cd:101::/64 lease-time default '86400'
set service dhcpv6-server shared-network-name pri101 subnet fc00:470:f1cd:101::/64 name-server 'fc00:470:f1cd:101::1'
set service dhcpv6-server shared-network-name pri101 subnet fc00:470:f1cd:101::/64 name-server 'fc00:470:f1cd::ff00'
```
This configuration does not seem to work. I use the lower level vyos2 as the sub route or PC. the configuration is as follows:
```
config
set interfaces ethernet eth0 address dhcpv6
```
Only addresses like the following can be obtained:
{F531933}
However, Linux mint, which uses Huawei router in working and bridging mode as the device link of the switch, can't get IPv6 at all. The reason is unknown. I thought it might be that Huawei router doesn't support IPv6, but the device in working and bridging mode shouldn't still use its routing function, so I chose to use my promox ve
The virtual machine takes DHCPv6 (over opnsense firewall virtual machine) directly from the main route of vyos1, but after waiting for a while, it can only get the suffix with the prefix of 128 that cannot be routed.
