Hallo ich versuche IPv6 am einem VDSL Anschluß mit einem Zyxel VMG1312-B30 als Modem zum Laufen zu bringen.

IPv4 funktioniert problemlos. Das Zyxel Modem macht das VLAN 7 Tagging. Feste IPv4 Adresse und fester IPv6 Adress Prefix im DSL Kundencenter konfiguriert.

interface GigabitEthernet1/1
description Telekom VDSL ohne VLAN7 TAG
nameif outside
security-level 0
pppoe client vpdn group VDSL
ip address pppoe setroute
ipv6 address autoconfig default trust dhcp
ipv6 address dhcp default
ipv6 enable
ipv6 nd managed-config-flag
ipv6 nd other-config-flag
ipv6 dhcp client pd ciscoasa

 show ipv6 interface outside ergibt:

# show ipv6 interface outside
outside is up, line protocol is up
IPv6 is enabled, link-local address is fe80::aaaa:xxxx:yyyy:zzzz
No global unicast address is configured

Joined group address(es):
ff02::1:ffef:xxxx
ff02::2
ff02::1
ICMP error messages limited to one every 100 milliseconds
ICMP redirects are enabled
ND DAD is enabled, number of DAD attempts: 1
ND reachable time is 30000 milliseconds
ND advertised reachable time is 0 milliseconds
ND advertised retransmit interval is 1000 milliseconds
ND router advertisements are sent every 200 seconds
ND router advertisements live for 1800 seconds
Hosts use DHCP to obtain routable addresses.
Hosts use DHCP to obtain other configuration.

Gibt es da ein Kochrezept was ich konfigurieren muss, damit es klappt
