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,

 

Bill

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.

 

So the process is:

1. PPPoE connected

2. SLAAC address assigned

3. RA received, default route added

4. DHCPv6 PD

 

This is the config I was using for DHCPcd:

interface pppoe

    ipv6rs

    ia_pd 1 wan/1 lan/2 dmz/3 lab/4 pppoe/5

 

 

Cheers,

Andre

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
