Hi guys, thanks for the answers...

Someone told me that a simple solution was just enable "ipv6
unicast-routing" on R2. And it worked fine

I really forgot this. We must remember that only "ip routing" is enable by
default.

Hi everybody,

I have the following topology and configuration:

 R1(s0/0) --IPv6-- (s1/0)R2(e0/0) --IPv4-- (e0/0)R3(Loopback2 -IPv6)

######### R3 ##########

But I got the following results:

So the tunnel works well between R2 and R3 routers, but I couldn't do this
lab work between R1 and R3. Does anybody has any idea ?

Thanks a lot.

Danilo
