As a part of proposal for distributed virtual routing
for VLAN networks through OVN, this series has code changes
for Layer 2.
[1] https://mail.openvswitch.org/pipermail/ovs-dev/2018-October/353066.html
[2] https://docs.google.com/document/d/1uoQH478wM1OZ16HrxzbOUvk5LvFnfNEWbkPT6Zmm9OU/edit?usp=sharing
This Series:
a. Changes in OVN NB Schema to introduce a logical switch type.
b. Changes in ovn-nbctl to configure a logical switch type.
c. Changes in ovn-northd to process and save a logical switch type.
Adding a logical switch type would be helpful in following:
a. Debugging, since VLAN backed logical switch is dependent on
localnet ports, hence basic validations like localnet port
configured or not etc., can be done with ease.
b. Helps with Layer 3 implementation
(https://mail.openvswitch.org/pipermail/ovs-dev/2018-October/353179.html).
This Patch:
a. Add 1 more column to the Logical_Switch table in north bound
schema, to indicate if a logical switch is of type "vlan" or "overlay".
We will support NULL value in this table as well, to keep it backward
compatible. NULL value will be treated as "overlay" type by northd.
b. Column name:
i. network_type: Represents whether network is vlan backed or
overlay.
