Abstract

A communications configuration comprising a first network medium having a first IP address and a second network having a second IP address. The configuration further includes a first host station with a first interface connected to communicate with the first network medium using the first IP address and a second interface connected to communicate with the second network medium using the second IP address. The configuration further includes a third network medium having a third IP address and a fourth network having a fourth IP address. Still further, the configuration includes a first router station coupled between the first network medium and the third network medium and a second router station coupled between the second network medium and the fourth network medium. Lastly, the configuration includes a second host station. The second host station includes a first interface connected to communicate with the third network medium using the third IP address and a second interface connected to communicate with the fourth network medium using the fourth IP address. The memory of the second host station is programmed to perform various steps. A first step detects a communications failure along a first communication path including the first interface of the first host station, the first network medium, the first router station, the third network medium, and the first interface of the second host station. A second step, responsive to the detected failure, redirects communications addressed to pass along a second communication path from the second host station to the first host station such that redirected communications are not attempted by the second host station to the first host station along the first communication path.
