Method and apparatus for path indication

Aspects of the disclosure provide a method for generating a Layer 2 path indication by a processor. The method includes receiving, by the processor, a request for providing a Layer 2 path indication between a first host and a second host in a network. Nodes in the network are configured to form a plurality of sub-networks to enable data transfer from one host to another host within a sub-network via a Layer 2 path formed of a sequence of intermediate nodes in the same sub-network. The method further includes identifying, by the processor, a sub-network within the network to which the first host and the second host belong, and determining, by the processor, within the sub-network a sequence of intermediate nodes on a path for Layer 2 data transfer between the first host and the second host.
