N-WAY VIRTUAL PORT CHANNELS USING DYNAMIC ADDRESSING AND MODIFIED ROUTING

摘要

Systems, methods, and non-transitory computer-readable storage media for dynamic addressing of virtual port channels is described. In some implementations, a virtual IP address can be dynamically generated based on which links in a virtual port channel are active. If the numbers of active links in the virtual port channel changes, the virtual IP address can be dynamically changed. The virtual IP address can be dynamically adjusted by changing the values of individual bits in the virtual IP address that correspond to links in the virtual port channel. The virtual IP address can be used as a tunnel end point address in a VXLAN environment.

1. A method comprising:
receiving, at a first network device, link state information from one or more second network devices in a virtual port channel peer group, the virtual port channel peer group including a plurality of network devices configured for a virtual port channel; setting, by the network device, a value of one or more bits in a virtual internet protocol address based on the received link state information; and advertising, by the network device, the virtual internet protocol address for the virtual port channel.
