Subject: Routing in case of GRE interface under a bridge

Hi,

I have a "l2gre0" and "eth0" interface under the bridge "br0". If a
packet comes to eth0 interface with a destination IP address say
10.10.10.1 which is not known on the Linux system, as there is no
route for 10.10.10.1, will the l2gre0 interface encapsulate this
packet and send it across the tunnel ?
The other endpoint is on a different Linux system with another l2gre0
interface having IP address 10.10.10.1

Thanks
N Gadre
