Hi,
I'm trying to config my Cisco 1941w to use IPv6. I have a IPv6 tunnel to SIXXs.net and IPv6 routing on wired interfaces works, but I can't reach the IPv6 interface of my LAN interface using the integrated AP. I can ping all the other IPv6 hosts in my network, but not the router itself.
The config:
interface GigabitEthernet0/1.10
description Data

ip virtual-reassembly in
ipv6 address <my IPv6 prefix>::1/64
ipv6 enable
ipv6 nd other-config-flag

Hello
I ran into the same issue with my 871. I actually had to configure IPv6 on the main radio interface instead of the bvi. Not ideal but for home it have been running for about a year now.

IPv6 support on BVIs only appaeared in recent 15.1T code.
