Abstract
A multilink trunk from a client device in a communication network is split between two aggregation devices such that each aggregation device is connected to at least one link of the multilink trunk. The aggregation devices work in conjunction to appear to the client device as a single device connected to the client device over the multilink trunk. The aggregation devices transmit identical bridge protocol data units to the client device over their respective links of the multilink trunk. The aggregation devices exchange operational information and data packets over inter-device communication ports. A failure of the split multilink trunk at one aggregation device is restored through the other aggregation device.
