Re: network verification (use case)

 

Our verify network feature (activated by corresponding button on networks
tab) verifies L2 connectivity of OpenStack networks. It configures desired
networking on bootstrap nodes, and runs UDP packets on required interfaces.
We also check for unwanted DHCP traffic. There are no checks on L3 layer at
the moment.

Thanks,
