Tunnel Zone

Ensure that the hosts running the MidoNet Agent have been added to the tunnel zone and are alive.

# midonet-cli

midonet> list tunnel-zone
tzone tzone0 name tz type vxlan

midonet> tunnel-zone tzone0 list member
zone tzone0 host host0 address 192.168.0.1
zone tzone0 host host1 address 192.168.0.2
zone tzone0 host host2 address 192.168.0.3
zone tzone0 host host3 address 192.168.0.4

midonet> list host
host host0 name host-a alive true
host host1 name host-b alive true
host host2 name host-c alive true
host host3 name host-d alive true

Check if packets are transmitted over the tunnel interface, and ensure that there are no errors or dropped packets.

Check the tnvxlan-overlay port in case of VXLAN protocol, or the tngre-overlay port in case of GRE protocol.
