Is there any possibility to connext Campus Fabric in a ring topology to each other ? (3 different Domains)

[redian_kasmolla]

We have built three domain campuses and we would like to connect these three in a ring topology.One idea was to use MRP in order to avoid looping, but there is a problem that does not allow us to group existing VLANs into one group (MRP isn't supported on Port extender).Error: "Vlan 10 has Spx-Pe ports, Can't be used in topology group."

Hey There, 

This looks like it could a bit complex for a forum post. If this is a design issue, I would recommend engaging you account team or Systems Engineer. You could also open a support case (see my signature) and we can try to help or point you in the right direction.
