公司搬家，从原有的思科设备换成华为AR路由器，有空研究了下华为AR路由器通过PPPoE拨号获取v6地址，且通过DHCPv6-PD给内网客户端分配地址。
全局开启IPv6
ipv6
基本PPPoE配置
interface Dialer1link-protocol pppppp chap user 011111063930ppp chap password cipher %^%#owP[R9/aFQA\~=4_*D+&N-ZU~$x&J$YIpz8<]3'G%^%#mtu 1492ipv6 enabletcp adjust-mss 1452ip address ppp-negotiatedialer user 011111063930dialer bundle 1ipv6 address auto link-local #自动配置链路本地地址ipv6 address auto global default #自动获取IPV6地址并添加默认路由nat outbound 3000 dhcpv6 client pd IPV6 #通过dhcpv6获取运营商前缀，前缀名称叫IPV6interface GigabitEthernet0/0/2pppoe-client dial-bundle-number 1 description To:ISPundo lldp enableacl number 3000 rule 5 permit ip source 192.168.0.0 0.0.255.255
配置IPV6的DHCP服务器给客户端下发DNS服务器地址
dhcpv6 pool IPV6dns-server 240E:5A::6666dns-server 240E:5B::6666dns-domain-name iteachs.com
配置路由器接口
interface GigabitEthernet0/0/1description To:Inside-IPV6
#

至此配置完成。

Secure FLAG : UN-SECURE 使用了一段时间没发现问题，从IPv6的流量上看，目前V6的流量是高于V4的。
