1. A routing information publishing method, comprising:
receiving, by an edge transport device, first routing information from a controller based on a control plane protocol message, wherein the first routing information comprises an address of a second edge device and a destination address of a second network domain, wherein the edge transport device is located in a transport network and the transport network is centrally controlled by the controller, wherein the transport network is used to connect a first network domain and the second network domain, the first network domain comprises a first edge device, the second network domain comprises a second edge device, and the edge transport device is connected to the first edge device; and
sending, by the edge transport device, the first routing information to the first edge device, wherein the first routing information is used to generate a routing table and an address resolution protocol (ARP) table of the first edge device, the routing and ARP tables are used to indicate a forwarding relationship between the first network domain and the second network domain, and wherein the transport network is of a first type of network, and the first network domain or the second network domain belong to a second type of network that is different from the first type of network.
