A load control system may include a network of devices configured to communicate with one another. The load control system may include control devices configured to operate as a leader device or another router device on the network. The control device may process advertisement messages from other router devices in the network. The control device may receive advertisement messages from non-leader router devices and compare the device identifier and the sequence number in the advertisement messages with the device identifier and the sequence number in previously-received advertisement messages from the non-leader router devices. The control device may process each advertisement message received with a different sequence identifier or a different device identifier than previously received advertisement messages from the non-leader router devices. The control device may ignore each advertisement message received with the same sequence identifier from the same non-leader router device as a previously received advertisement message.
