[ovs-discuss] Query regarding flow removal on OpenvSwitch when link between two switches is down

[Saloni Jain]

Hi All,

Kindly provide inputs on following scenario:

There are 4 OpenvSwitches S1,S2,S3,S4 interconnected with each other such
that there are links between S1-S2, S2-S3, S3-S4 and S4-S1 and all the 4
switches are connected to Controller.

Packet comes from S2 to S4 and accordingly flows are written by controller
on switches S2,S3 and S4 following the path S2-S3-S4 and communication
starts.

Suppose the link between S3-S4 goes down, so will the flows corresponding
to S2-S3-S4 path should remain on these switches or should get deleted by
the controller as now the link between S3 and S4 is down?

Thanks in advance for your help.

Thanks and Regards,
Saloni Jain
