+# This test is for checking the VXLAN vni filtering api and
+# datapath.
+# It simulates two hypervisors running two VMs each using four network
+# six namespaces: two for the HVs, four for the VMs. Each VM is
+# connected to a separate bridge. The VM's use overlapping vlans and
+# hence the separate bridge domain. Each vxlan device is a collect
+# metadata device with vni filtering and hence has the ability to
+# terminate configured vni's only.
