1. A network device comprising:
a memory; and a processor, wherein the processor is configured to: configure a communication channel through a virtual IP address; designate a first global site selector as a primary device for probing the virtual IP address; designate a second global site selector as a standby device for probing the virtual IP address, wherein the first global site selector and the second global site selector are part of a mesh comprising a plurality of global site selectors; receive a pull request at the first global site selector and the second site selector from one of the plurality of global site selectors, wherein the pull request comprises a request for the status of the virtual IP address stored on the primary global site selector and the status of the virtual IP address stored on the standby global site selector; and derive an combined virtual IP address status from the status of the virtual IP address stored on the primary global site selector and the status of the virtual IP address stored on the standby global site selector, wherein deriving the combined virtual IP address status comprises computing the logical AND of the status of the virtual IP address stored on the primary global site selector and the status of the virtual IP address stored on the standby global site selector. |
