with a 3 node cluster with ovsdb southbound installed, a bridge cannot be created.

this is coming from a failure in CSIT:

ovsdb-csit-3node-clustering-only-beryllium

3 node cluster, each node installs:
odl-mdsal-clustering
odl-ovsdb-southbound-impl-rest

OVS control is configured like this:
sudo ovs-vsctl set-manager tcp:

{IP1}:6640 tcp:{IP2}:6640 tcp:{IP3}:6640

The PUT can be sent to any of the controllers, but the URI is:
http://{IP}:8181/restconf/config/network-topology:network-topology/topology/ovsdb:1/node/ovsdb://uuid/{UUID}/bridge/brtest

The PUT data in CSIT is this:
{
"node": [
{
"node-id": "ovsdb://uuid/{UUID}/bridge/br01",
"ovsdb:bridge-name": "br01",
"ovsdb:protocol-entry": [
{ "protocol": "ovsdb:ovsdb-bridge-protocol-openflow-13" }
],
"ovsdb:controller-entry": [
{
"target": "tcp:{IP1}

:6640"
},
{
"target": "tcp:

{IP2}

:6640"
},
{
"target": "tcp:

{IP3}

:6640"
}
],
"ovsdb:bridge-other-configs": [

{ "bridge-other-config-key": "datapath-id", "bridge-other-config-value": "0000000000000001" }

],
"ovsdb:managed-by": "/network-topology:network-topology/network-topology:topology[network-topology:topology-id='ovsdb:1']/network-topology:node[network-topology:node-id='ovsdb://uuid/

{UUID}

']"
}
]
}

The following ERROR is seen in the karaf.log of each controller after each PUT. It comes with each
DELETE as well:
