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

Most of communication was done offline.

Fixed with commit: https://github.com/cloudbase/ovs/comm...

The issue was we were not clearing the route cache properly and did not apply a hard match on the source IP.

Thanks, Alin.
