These virtual service topologies allow a sequence of service nodes to be visited across multiple zones in a data center to form a service chain. The method uses service topology specific Route Targets (RTs) in addition to general purpose RTs. Provisioning with Software Defined Network (SDN) controller is discussed in this document.}, }
