Clusters and Open vSwitch

phpHavok — Fri, 01 Jul 2016 20:44:43 GMT

I have a topology with 4 switches (Linux machines running Open vSwitch) connected in a diamond shape like follows:
A connects to B and C
B connects to D
C connects to D

Since A, B, C, and D all have a path to each other, I would expect this topology to appear as a single cluster in VAN. However, VAN is representing this topology as 4 individual clusters, one for each switch. Does anyone know what's going on here?

Thanks!

My apologies for not seeing this sooner ... could you post the REST API output of the following REST call?

https://$CTRL_IP:8443/sdn/v2.0/net/links

I would expect for these switches to all be part of the same topology cluster. When you refer to clusters, are you meaning visually (in the VAN "OpenFlow Topology" GUI) or are you meaning in the REST API for clusters?
