[ovs-dev] Q on ovs-dpdk + Vxlan user space tunneling

I am going through following link and setting up the testbed


and it is very confusing to me at least. Can someone please clarify
following questions?

(1) I believe flows needs to be programmed on br-int bridge with
in_port=vm_port0, out_port=vxlan0, vice-versa. When bridge is created it
has a default flow with NORMAL action, i don't think this suffices?

(2) How do packets flow from br-int to br-phy and br-phy to br-int?

(3) Link says add following route

"ovs-appctl ovs/route/add br-eth1"

What is br-eth1? I don't see anything about it in the link?

(4) Assuming br-eth1 is br-phy, I tried to add route on the testbed I
am configuring I get

ovs-appctl ovs/route/add br1-phy
Error while inserting route.
ovs-appctl: ovs-vswitchd: server returned an error
