====== Ativando IPv6 CPE Mikrotik com PPPoE ======

Para executar as configurações abaixo é necessário ter o pacote IPv6 ativado.

Primeiro devemos configurar o dhcp-client na interface PPPoE client e criar o Pool de IPs.
  /ipv6 dhcp-client
    add add-default-route=yes interface=pppoe-out1 pool-name=dhcp-pd pool-prefix-length=64 request=prefix

Após é necessário configurar o IPv6 da interface LAN.
  /ipv6 address
    add address=::1/64 from-pool=dhcp-pd interface=ether2

Configurar o ND (Neighbord Discovery).
  /ipv6 nd
    set [ find default=yes ] advertise-dns=yes other-configuration=yes

Também é necessário configurar as regras de firewall para IPv6.
  /ipv6 firewall filter

    add chain=input comment="Libera multicast" src-address=ff00::/8
    add chain=input comment="Libera link local" src-address=ff00::/10
    add chain=input comment="Libera multicast" dst-address=ff00::/8
    add chain=input comment="Libera link local" dst-address=ff00::/10
    add chain=input comment="Libera icmp" in-interface=pppoe-out1 limit=200,5:packet protocol=icmpv6
    add chain=input comment="Libera DHCPv6" dst-port=546 in-interface=pppoe-out1 limit=200,5:packet protocol=udp
