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.


Interface tunnel IPv6-in-IPv4

Interface ini biasanya di kenal dengan nama sitx. Nama sit adalah kependekan dari Simple Internet Transition. Device ini mempunyai kemampuan untuk mengenkapsulasi paket IPv6 ke dalam paket IPv4 dan mengirimkan melalui tunnel ke ujung satu-nya.

sit0 mempunyai arti spesial dan tidak dapat digunakan untuk tunnel khusus.

Interface PPP

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

Others

Did I forget an interface?...
