Methods and systems for automatically rerouting logical circuit data
An example involves selecting a logical failover circuit comprising an alternate communication path for communicating data upon a failure of a dedicated logical circuit connecting a host device to a remote device. When a first logical circuit identifier of the dedicated logical circuit does not match a second logical circuit identifier of the logical failover circuit: the second logical circuit identifier of the logical failover circuit is renamed to identify the logical failover circuit using the first logical circuit identifier when the logical failover circuit is a dedicated logical failover circuit used to communicate only when the dedicated logical circuit fails, and the dedicated logical circuit is renamed to identify the dedicated logical circuit using the second logical circuit identifier when the logical failover circuit is used to communicate regardless of the failure of the dedicated logical circuit. The data is rerouted to the logical failover circuit without manual intervention.
