Reproduced here. Seems like ioctl() does everything correctly and returns no
error when creating new tunnel over an existing one, so it's not internall
problem of iproute. Will need some rework for iproute or changes in ioctl ..
Comment 4 Radek Vokál 2005-10-31 10:56:12 UTC 
Ok, I've added a warning message when tunnel already exists, please check
iproute-2.6.14-7
