It is possible to setup Linux GRE for Ethernet frames but you need to
use the ip link command with a type of "gretap". However, due to a
number of correctness and performance issues (or no support at all)
that vary across Linux kernel versions, we don't support/recommend
using the Linux GRE implementation.
OK, thanks for the clarification. I see now why that wasn't working.

Leave A as-is, setup GRE using ovs-vsctl on B.
Ping from B doesn't work. I see GRE packets (ARP) going out eth0 on B
and coming in eth0 on A but nothing on the vbr2 bridge.
This configuration would normally work. However, multicast isn't
currently implemented in the Open vSwitch GRE stack. It's planned and
it shouldn't be too much work but it hasn't been done yet.
Do you have any idea when it might be available?
Thanks,
Mike
