Abstract

Aspects of the subject disclosure relate to methods for detecting a link failure between the first network device and a destination node, receiving a data packet addressed to the destination node, and rewriting encapsulation information of the first data packet. Subsequent to rewriting the encapsulation information of the first data packet, the first data packet is forwarded to a second network device (e.g., using updated address information in the packet header), wherein the second network device is paired with the first network device in the virtual port channel. In certain aspects, systems and computer readable media are also provided.
