Abstract: Upon receiving a first message, from the second network device, indicating that the second network device is incompatible with one or more virtual local area network (VLAN) pruning techniques, a timer on a first network device is configured to expire after a predetermined period of time. The first network device is configured to maintain a subscription for the second network device to one or more VLANs until the timer expires. The second network device is configured to transmit the first message in response to detecting an upcoming control plane outage at the second device. Prior to the timer expiring, embodiments transmit data assigned to the one or more VLANs to the second network device. Embodiments also periodically receive update messages, from the second network device, identifying one or more VLANs to which the second network device wants to subscribe.
