On the subinterface I see an address
2degrees10 is up, line protocol is up
IPv6 is enabled, link-local address is fe80::26e9:b3ff:fe92:d96
No global unicast address is configured
Joined group address(es):
ff02::1:ff92:d96
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 stateless autoconfig for addresses.
Which is the same interface the ipv4 address comes up on:
Interface GigabitEthernet0/7.10 "2degrees10", is up, line protocol is up
Hardware is i82574L rev00, BW 1000 Mbps, DLY 10 usec
VLAN identifier 10
Description: 2degrees
MAC address 24e9.b392.0d96, MTU 1492
IP address xxx.xxx.xxx.xxx, subnet mask 255.255.255.255
Traffic Statistics for "2degrees10":
258001448 packets input, 203508132527 bytes
152127591 packets output, 123285082718 bytes
971621 packets dropped
With an ipv6 route set:
L fe80::/10 [0/0]
via ::, 2degrees10
L ff00::/8 [0/0]
via ::, 2degrees10
but I don���t get anything else, I���ll try doing some debug over the weekend.
Thanks,

Took me a while to get it working on my Linux router, but if I remember correctly, you can't request address allocation on the DHCP request. Needs to be PD only, else the DHCP server won't reply (something to do with the client excluding the address allocation from the PD request and the server not supporting the option, or the other way around).
The other thing I noticed was that DHCPv6 only worked after I had received the RA from the gateway and the default route was inserted.
2. SLAAC address assigned
3. RA received, default route added
This is the config I was using for DHCPcd:
ia_pd 1 wan/1 lan/2 dmz/3 lab/4 pppoe/5

Hi All,
I���ve been quite happily running a Cisco router at home on Snap/2degrees, but with the upgrade to UFB its not coping with the throughput. I���ve managed to locate a suitably equipped ASA, however I cant get IPv6 going. The config I have on the ASA is very similar to that of the router:
nterface GigabitEthernet0/7
description 2degrees
nameif EXTERNAL
security-level 0
no ip address
ciscoasa# sh run int gi0/7.10
!
interface GigabitEthernet0/7.10
description 2degrees
vlan 10
nameif 2degrees10
security-level 0
pppoe client vpdn group 2degrees
ip address pppoe setroute
ipv6 address autoconfig
ipv6 address dhcp
ipv6 enable
ipv6 dhcp client pd 2degrees-v6
However, if I remember correctly the IPv6 dhcp assignment happens inside the PPPoE connection once its established. Can anyone confirm that or provide a working config?
In case someone wants versions, the ASA is on 9.9.2 (asa992-smp-k8.bin)
Thanks,
Bill
