Abstract
An example method for a first host to perform traffic replication in a software-defined networking (SDN) environment may include obtaining control information that includes a first identifier associated with a first replication domain to which the first host and a second host are assigned, and a second identifier associated with a second replication domain to which a third host is assigned. In response to detecting, from a virtualized computing instance, a packet that requires replication, the method also includes, generating a first encapsulated packet by encapsulating the packet with a first outer header that includes the first identifier, generating a second encapsulated packet by encapsulating the packet with a second outer header that includes the first identifier or the second identifier, and sending the first encapsulated packet to the second host, and the second encapsulated packet to third host to cause the third host to perform replication within the second replication domain.
