BIRD unable to read data from TUN/TAP device
Hi I'm trying to let BIRD communicate over virtual network devices created by the Linux TUN/TAP module. As it seems the tap devices receive the messages from BIRD. However, BIRD does not seem to receive the messages sent to it over the tap device. I described the scenario and the issues I run into in more detail on stackoverflow. If somebody has some experience with running BIRD over TUN/TAP devices, please take a look here: http://stackoverflow.com/questions/21001713/linux-tun-tap-unable-to-read-dat... Much thanks to anybody that can provied me with some insights into the issue! Best, Cyrill

I am not sure if i understand your scenario, but if you run both TUN/TAP endpoints on one machine, i would be surprised if OS network code wouldn't be confused by that. If not, you should try ping and try to run OSPF in NBMA mode (which will use just unicasts).
If somebody has some experience with running BIRD over TUN/TAP devices,
Generally, it works over OpenVPN tunnels, which use TUN/TAP devices, but in that cases both endpoints are on different machines. -- Elen sila lumenn' omentielvo Ondrej 'SanTiago' Zajicek (email: santiago@crfreenet.org) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so."
