IPv6 on 1941w

GJ.NoscoICT
Level 1
Level 1

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

encapsulation dot1Q 10

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.

Look up  CSCta27529 on Bug Navigator.
