Some embodiments provide a method and system for configuring a plurality of managed forwarding elements (MFEs) in a plurality of cloud-provider virtual networks (CPVNs) to make routing decisions that efficiently use a peered transit CPVN and peering with other CPVNs in the plurality of CPVNs. In some embodiments, a controller set receives an identification of peering relationships between CPVNs in the plurality of CPVNs and generates configuration data for configuring each MFE. The configuration data is used to configure the MFE to forward data messages received at the MFE using a peering between a source CPVN and a destination CPVN when possible and to forward data messages received at the MFE to a transit gateway device in a transit CPVN when it is not possible to use a peering between the source and destination CPVNs.
