Eu tentei adicionar um bloco inteiro IPv6 (/ 64) a uma interface usando
ip route add local 2001:41d0:2:ad64::/64 dev lo
como descrito aqui no meu servidor Debian, mas pareço estar faltando alguma coisa.
Se eu pingar por exemplo 2001:41d0:2:ad64::fe
localmente, tudo funciona bem, mas se eu tentar de uma máquina remota, não funciona.
Eu tentei adicionar a rota em eth0:
ip route add local 2001::41d0:2:ad64::/64 dev eth0
Agora eu não pude nem mesmo digitar qualquer endereço de exemplo localmente!
Estou um pouco perdido, pois parece que estou perdendo alguma coisa, mas não consigo encontrar a resposta aqui.
Para breve:
Eu quero que 2001:41d0:2:ad64::/64
seja vinculado a eth0 para que todos os IPs que este bloco contém sejam acessados pela internet em minha máquina.
Espero que alguém possa me indicar o caminho certo.
Agradecemos antecipadamente.
O guia fornecido pelo ISP requer que eu adicione cada IPv6 à interface explicitamente. Eu quero que seja implícito.

Solução nº 1
Eu tentei reativar a rota local como sugerido pelo @kasperd.
