CISCO and IPV6 Support BVI
![[it]](/s/countries/it.gif) Shadow Hawkins on Friday, 09 February 2007 16:40:51
Hello everybody,
did you know that Cisco doesn't support IPV6 as well ??
IPV6 is not supported yet on wireless interface !!!
so is not possible to bridging IPV6 between BVI and others !!???
Please see case : CSCej50923: IPv6 IRB support - BVI interfaces
If anybody as a suggestion or a workaround is welcome!
ciao
lorenzo

Hello Lorenzo,
I wasn't able to locate that cisco bug CSCej50923 or the text IPv6 IRB support. I do not have a wireless interface to test on the 2621, but was able to get IPv6 to work on a BVI interface.

I have a c871w and non working ipv6 bvi interface. My workaround is to tunnel ipv6 accross a gre tunnel I build. I have the sixxs tunnel endpoint on a Ubuntu box. This box is connect to the router via the bvi interface. Here is the gre tunnel setup:
Ubuntu box:
auto tun0
iface tun0 inet static
address 10.1.0.1
netmask 255.255.255.252
pre-up iptunnel add tun0 mode gre local <local interface ip> remote <bvi interface ip> ttl 255
up ifconfig tun0 multicast && ip -6 route add 2001:6f8:<your /56 prefix>:2::/64 dev tun0
pointopoint 10.1.0.2
post-down iptunnel del tun0
Cisco router:
interface Tunnel0
ip address 10.1.0.2 255.255.255.252
ipv6 enable
tunnel source BVI2
tunnel destination <ubuntubox interface ip>
tunnel path-mtu-discovery
ipv6 route ::/0 Tunnel0
