OVS bridge patching for Neutron

edit

Was having issues w DHCP and metadata from our controller and found Discovers are broadcast on br-int, but watching br-tun where the vxlan tunnel ports are connected I don't see the broadcasts reflected. What am I missing here?

br-int
Port patch-tun
Interface patch-tun
type: patch
options:
{peer=patch-int}
