Patent ID: 7940646

Claim:
A method comprising: receiving, with a network device, a plurality of routing information protocol (RIP) updates each having a metric value; signaling a plurality of bidirectional forwarding detection (BFD) sessions based on the metric value of each RIP update, wherein signaling the plurality of BFD sessions includes signaling one of the plurality of BFD sessions is signaled as an active session; selectively installing, with the network device, a RIP route in routing information maintained by a control unit based on the metric value; and performing non-revertive failover with the network device in the event one of the plurality of BFD sessions fails, wherein performing non-revertive failover includes: receiving a second plurality of RIP updates each having a metric value; signaling the active one of the plurality of BFD sessions as standby based on the metric values of the second plurality of RIP updates; and uninstalling the RIP route from the routing information maintained by the control unit based on the metric values of the second plurality of RIP updates.
