Hi
Is possible to transport ipv4 and ipv6 addresses in the same tunnel interface?
If I debug the tunnel of the hub with debug tunnel comand , I recive this output.
R1-Hub#ping 2001:db8::2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001:DB8::2, timeout is 2 seconds:
*Apr 20 12:36:50.128: Tunnel0: Drop, Encap failed, pak if = Tunnel0,desthost 0.0.0.0, linktype 79.
*Apr 20 12:36:52.133: Tunnel0: Drop, Encap failed, pak if = Tunnel0,desthost 0.0.0.0, linktype 79.
*Apr 20 12:36:53.224: Tunnel0: Drop, Encap failed, pak if = Tunnel0,desthost 0.0.0.0, linktype 74
*Apr 20 12:36:54.137: Tunnel0: Drop, Encap failed, pak if = Tunnel0,desthost 0.0.0.0, linktype 79.
*Apr 20 12:36:56.139: Tunnel0: Drop, Encap failed, pak if = Tunnel0,desthost 0.0.0.0, linktype 79.
*Apr 20 12:36:58.143: Tunnel0: Drop, Encap failed, pak if = Tunnel0,desthost 0.0.0.0, linktype 79.
Success rate is 0 percent (0/5)

Thanks
EDIT…
I was able to configure the ipv6 and ipv4 in the same tunnel.
