# See ovn-controller-vtep(8) for details about ovn-controller-vtep.
#
# You may override the following variables to customize ovn-controller-vtep
# behavior:
#
#   OVN_DB - Set this variable to the location of the ovsdb server that is
#            serving the OVN_Southbound database.  See the manpage for
#            ovn-controller-vtep for more details on the format for the db
#            location.
#
#   VTEP_DB - Set this variable to the location of the ovsdb server that is
#             serving the hardware_vtep database.  See the manpage for
#             ovn-controller-vtep for more details on the format for the db
#             location.
#
# To override these variables, you may create a configuration file
# in the /etc/systemd/system/ovn-controller-vtep.d/ directory.  For example,
# you could place the following contents in
# /etc/systemd/system/ovn-controller-vtep.d/local.conf:
#
#   [System]
#   Environment="OVN_DB=unix:/usr/local/var/run/openvswitch/db.sock" "VTEP_DB=unix:/usr/local/var/run/openvswitch/vtep.sock"
#
# Alternatively, you may specify environment variables in the file /etc/sysconfig/ovn-controller-vtep:
#
#   OVN_DB="unix:/usr/local/var/run/openvswitch/db.sock"
#   VTEP_DB="unix:/usr/local/var/run/openvswitch/vtep.sock"
