Virtual port channel bounce in overlay network

摘要

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.

主权项

1. A computer-implemented method comprising:
detecting, by a first network device in a virtual port channel, a link failure between the first network device and a destination node; receiving, by the first network device in the virtual port channel, a first data packet addressed to the destination node; and in response to detecting the link failure between the first network device and the destination node, rewriting, by the first network device, encapsulation information of the first data packet, wherein rewriting the encapsulation information of the first data packet causes the first data packet to be forwarded to a second network device, wherein the second network device is paired with the first network device in the virtual port channel.
