Problems getting an ipv6 address though PPPoE

"PPPoe" | |

DSL GigE interface Vlan 998

Hi all,

I want to connect a Cisco 877 using “PPPoE” to a 1941 router and get an Ipv6 address. When I use a Ipv4 address on my connection I am able to authenticate and get a “192.168.0.7” Ipv4 address successfully, but when I remove the Ip4 address 192.168.0.7 and try to connect to the router using an IPV6 address I am not getting and IPv6 Address by DHCP, even If I manually assign an Ipv6 address to my modem on my 1941 it does not shows that Ipv6 address is being used by CE2 user. I am able to authenticate but I am not being assign an Ipv6 address. Attached are the configuration for my 1941 and 877, any help is highly appreciated.

Thanks,

Danny Itza

This is the “ ipv4” address i am getting after I authenticate successfully

IPv6_3845-DsRTR#show users

Interface User Mode Idle Peer Address

Vi4 CE2 PPPoE 00:00:00 192.168.0.7

This is the result when I try to connect using an "IPv6 address" I am not being assign an IPv6 address

IPv6_3845-DsRTR#show users

Interface User Mode Idle Peer Address

Vi4 CE2 PPPoE 00:00:00

Below are the results I get when I run a “ debug ppp negotiation” and “debug dhcp detail”

Results when I try the PPPoE connection using Ipv4 address, I am able to get and IPv4 address 192.168.0.3 successfully.
