Well, the question is given. I have tap0 interface connecting to a server which provides IPv6 addresses. I would like to set my RDNSS settings in radvd config and I need the logical interface name of tap0 to do that.

  • I am not sure what you mean with logical interface name but the interface name for tap0 is just tap0. You can check with brctl if tap0 is attached to the lan or wan bridge – Ulrich Dangel Feb 21 '13 at 10:18
  • There is a /etc/config/network file in my system, where every interface I intend to use has a logical interface name. This ifname is a free pick. In /etc/config/radvd config interface settings are referenced by this logical interface name. The problem is that openvpn creates tap0 therefore I cant specify a logical interface name for that, could I? – roncsak Feb 21 '13 at 11:45
