<p>A router fault tolerant network interface system (300) includes a switch circuit (302) configured to detect when a router fails in a multi-router local network. When a failed router (202) is detected, the switch circuit (302) waits for a time-out period to expire to allow convergence. The switch circuit (302) then intervenes when traffic from a server (106) to the failed router (202) is detected. The switch circuit (302) translates the MAC address of the failed router (202) to the MAC address of a functional router (104). Traffic from a server (106) originally directed to the failed router (202) is then redirected to a functional router (104). In a further refinement, the switch circuit (302) provides the MAC address of a functional router (104) in response to an ARP request from a server (106) to the failed router (202).</p> |
