EdgeRouter-X PPPoE IPv6+三組VIF網段 ipv6-test.com後面兩組VIF顯示ipv6不支持

想請教各位大神請問有人試過在VIF介面上開啟ipv6 SLAAC+DHCPv6 PD方式讓後端的設備也取得IPv6位置,小弟目前設定後遇到狀況如下:
VLAN2網段的設備ipv6-test.com 測試IPv4 & IPv6顯示都可以支持
但其他的VLAN3 & 4的設備卻只能顯示IPv4支持 IPv6不支持

目前設定如下
WAN: pppoe0 (eth1)
LAN:eth1~4(switch0)
switch0.2 =192.168.2.254/24=VLAN2
switch0.3 =192.168.3.254/24=VLAN3
switch0.4 =192.168.4.254/24=VLAN4
奇怪的VIF2~4 的IPv6 address都是相同的

[VLAN2 ipv6-test]

[VLAN3 ipv6-test]
