Abstract
A mobility network architecture includes a control plane and data plane. The control plane supports notification of VLAN configurations. The data plane supports routing of data amongst VLANs. Each VLAN has an associated identifier value as well as a version number. The version number for a respective VLAN can be updated to a new value each time there is a change to the VLAN. Typically, a controller communicates over the control plane to notify each member switch when a version number has changed for a VLAN. If controller notification fails, a member switch can receive a notification from a neighboring switch that the version number for a VLAN has been modified. In response to detecting such a condition, the switch receiving the notification can prevent forwarding of data even though the switch does not receive notification from the controller that the version number for the VLAN has changed.
