IPv6: Network Devices yang berbeda
Pada sebuah node, ada beberapa device network. Mereka tergabung dalam beberapa kelas.
- Secara fisik, seperti eth0, tr0
- Secara virtual, seperti ppp0, tun0, tap0, sit0, isdn0, ippp0
Secara Fisik
Menempel secara fisik seperti Ethernet atau Token-Ring secara normal tidak memerlukan penanganan khusus.
Secara Virtual
Interface yang menempel secara virtual biasanya membutuhkan dukungan khusus.
IPv6-in-IPv4 tunnel interfaces
These interfaces are normally named sitx. The name sit is a shortcut for Simple Internet Transition. This device has the capability to encapsulate IPv6 packets into IPv4 ones and tunnel them to a foreign endpoint.
sit0 has a special meaning and cannot be used for dedicated tunnels.
PPP interfaces
PPP interfaces get their IPv6 capability from an IPv6 enabled PPP daemon.
ISDN HDLC interfaces
IPv6 capability for HDLC with encapsulation ip is already built-in in the kernel
ISDN PPP interfaces
ISDN PPP interfaces (ippp) aren't IPv6 enabled by kernel. Also there are also no plans to do that because in kernel 2.5.+ they will be replaced by a more generic ppp interface layer.
SLIP + PLIP
Like mentioned earlier, this interfaces don't support IPv6 transport (sending is OK, but dispatching on receiving don't work).
Ether-tap device
Ether-tap devices are IPv6-enabled and also stateless configured. For use, the module “ethertap” has to be loaded before.
tun devices
Currently not tested by me.
ATM
01/2002: Aren't currently supported by vanilla kernel, supported by USAGI extension
