Classification: CPC H | IPC H

Claim 7:
8. A first network device comprising:
one or more processors;
one or more network interfaces; and
at least one memory storing instructions that, as a result of execution by the one or more processors, cause the first network device to:
operate in a first mode in which the first network device is configured to process network traffic according to a first communication protocol and to process network traffic according to a second communication protocol;
receive, from a second network device, first routing information regarding a first route associated with a first host device in a first data center, the first route including an address of the second network device formatted according to the second communication protocol;
install the first route in a routing table stored in the at least one memory of the first network device;
generate a second route that includes an identifier of the first network device formatted according to the first communication protocol;
export the second route to a third network device over one or more external networks;
receive, from the third network device, an encapsulated data packet having an overlay that includes the identifier;
replace, in the overlay, the identifier with the address based on the first route stored in the routing table of the first network device; and
send a re-encapsulated data packet to the second network device.
