Abstract:
Example methods are provided for a first routing component to handle failure at a logical router in a first network. One method may comprise learning first path information associated with a first path provided by an active second routing component, and second path information associated with a second path provided by a standby second routing component. The method may also comprise in response to detecting a first egress packet destined for a second network, sending the first egress packet to the active second routing component based on the first path information. The method may further comprise in response to detecting a failure at the active second routing component and detecting a second egress packet destined for the second network, sending the second egress packet to a new active second routing component based on the second path information.
