I have 3 node setup , each node having 2 NICs & I am not able to ping/ssh to instances (security group rules are created)

• controller private ip 10.211.20.50/ public ip XX.XXX.111.31
• network private ip 10.211.20.51/ public ip XX.XXX.111.32
• compute private ip 10.211.20.52/ public ip XX.XXX.111.33

On compute node 'openvswitch-agent.log' shows an error

ERROR [quantum.agent.linux.ovs_lib] Unable to execute ['ovs-vsctl', '--timeout=2', 'add-port', 'br-tun', 'gre-3']. Exception:
Command: ['sudo', 'quantum-rootwrap', '/etc/quantum/rootwrap.conf', 'ovs-vsctl', '--timeout=2', 'add-port', 'br-tun', 'gre-3']
Exit code: 1
Stdout: ''
Stderr: 'ovs-vsctl: cannot create a port named gre-3 because a port named gre-3 already exists on bridge br-tun\n'

Here are the details from database
