Hi JamO Thank you for the answer. As far as I see the only way to handle mesh topologies with Opendaylight Fluorine is to enable the native spanning tree algorithms available in the switches. Otherwise the network collapses due to ARP floods. I enabled the spanning tree in the switches and saw that the switches block some of the links to break the loops and inform the controller as if these links do not exist. Therefore ODL Fluorine cannot do shortest path routing between the source destination pairs when their shortest paths should pass through these blocked links. Moreover the average link utilization may increase as the number of links in the network decreases.

Use an older release for that, is all I can suggest at this time. Thanks, JamO On 12/13/18 12:35 PM, Dun Dun wrote: > Hi > > L2switch is not included in Fluorine.
