Abstract
Example methods are provided to handle failure at one or more logical routers according to a non-preemptive mode. The method may include in response to detecting, by a first routing component operating in a standby state, a failure associated with a second routing component operating in an active state, generating a control message that includes a non-preemptive code to instruct the second routing component not to operate in the active state after a recovery from the failure, sending the control message to the second routing component, and performing a state transition from the standby state to the active state. The method may also include in response to detecting, by the first routing component operating in the active state, network traffic during the failure or after the recovery of the second routing component, forwarding the network traffic from the first network to the second network, or from the second network to the first network.
