The following describes OVS bridge configurations supported by OpenDaylight.
If the br-int bridge is not configured prior to the ovsdb manager connection with ODL,
ODL will create it. If br-int exists prior to the ovsdb manager connection, ODL will retain
any existing configurations on br-int. Note that if you choose to create br-int prior to
connecting to ODL, disable-in-band
MUST be set to true and any flows configured may interfere
with the flows ODL will create. ODL will add the following configuration items to br-int:
It is important to note that once the ovsdb manager connection is established with ODL, ODL “owns” br-int and other applications should not modify its settings.
Provider networks should be configured prior to OVSDB connecting to ODL. These are configured
in the Open_vSwitch table’s other_Config column and have the format <physnet>:<connector>
where <physnet>
is the name of the provider network and <connector>
is one of the following
three options:
For example, assume your provider network is called extnet and it is attached to the eth0 interface on your host you can set this in OVSDB using the following command:
sudo ovs-vsctl set Open_vSwitch . Other_Config:provider_mappings=extnet:eth0
If instead of eth0
the provider network is accesable via on OVS bridge called br-int
, eth0
in the
above command would be substituted with br-int
.
