Claim Text:
1. An information handling device comprising: a plurality of interfaces; and a memory including a first routing table, the first routing table being associated with a first virtual routing and forwarding (VRF) instance, the first VRF instance providing a normal-condition path associated with a network address; and one or more processors in communication with the plurality of interfaces and the memory, wherein the one or more processors are configured to: receive, from a network controller and prior to a network failure being detected, a reroute path associated with the network address and a policy-based routing rule indicating that the traffic corresponding to the network address should be associated with a second VRF instance, wherein the network controller is an OpenFlow controller and the reroute path and the policy-based routing rule are received according to an OpenFlow protocol; store the reroute path in the memory using a second routing table, the second routing table being associated with the second VRF instance; and disassociate the network address from the first VRF instance and associate the network address with the second VRF instance when the network failure is detected.
