Hi,

a machine otherwise having IPv6 connectivity using Ethernet (ep0) has
been given an experimental (gif) tunnel.

Now, packets going out the default route (via Ethernet) get the gif0
address as the source address.

Is something fishy going on in the source address selection code? Did=20
I forget some magic switch?
