description Some embodiments provide a method for implementing a logical router that spans multiple datacenters. The method receives a configuration for a set of logical switches and a logical router (LR) that (i) handles data traffic between data compute nodes (DCNs) connected to the logical switches and endpoints not connected to the set of logical switches and (ii) performs stateful services on the traffic. The DCNs include at least one DCN operating in each datacenter. For each datacenter, the method defines a centralized routing component (SR) for the LR for handling the traffic between the DCNs in the datacenter and the endpoints not connected to the set of logical switches. The method designates one of the SRs as a primary SR and the other SRs as secondary SRs. The secondary SRs forward traffic, received from DCNs in their respective datacenters and for which stateful services are required, to the primary SR.
