You would need tunnel endpoints to complete tunnel setup.
add-port br0 tep0 -- set interface tep0 type=internal (in each switch)
Assign a private subnet IP on tep0 (different than 192.168.1.x) and then
you would see GRE encapsulated packets
on pinging tep0.

Hi Ben,
I have used normal "ping" to generate traffic.
From S1 I tried to ping S2 using "ping 192,168.1.1"

What did you use to direct traffic into the tunnels?
