Multipoint GRE

[Clint Armstrong]

Is it possible to create a point to multipoint GRE network on FreeBSD?

On Linux I would do this by creating the GRE interface without a defined
tunnel endpoint. Then by adding psudo-arp entries which map addresses on
the GRE subnet with a tunnel endpoint address I can have multiple GRE
tunnel destinations.

Based on my testing so far, it looks like GRE on FreeBSD requires a single
tunnel endpoint address. Is there any way around this?
