installing the first set of routes in a data structure stored in a local memory of the first network device;
generating a second set of routes that include a second address of the first network device formatted according to the first communication protocol;
exporting the second set of routes to a third network device in a second data center;
receiving, from the third network device, an encapsulated data packet having an overlay that includes the second address;
de-encapsulating and replacing, in the overlay, the second address with the first address based on the first set of routes stored in the data structure; and
