Dear Bruce

Thank you for a prompt response.

The command you give will set the two ends of the GIF connection and we 
are using it, but it is not the command that sets the physical ends of 
the tunnel.

We would expect something of the form

gifconfig_gif0="fec0::1 fec0::2"

but there appears to be no ipv6 form
