摘要： Presented herein are techniques for use in a network environment that includes one or more service zones, each service zone including at least one instance of an in-line application service to be applied to network traffic and one or more routers to direct network traffic to the at least one service, and a route target being assigned to a unique service zone to serve as a community value for route import and export between routers of other service zones, destination networks or source networks via a control protocol. An edge router in each service zone or destination network advertises routes by its destination network prefix tagged with its route target. A service chain is created by importing and exporting of destination network prefixes by way of route targets at edge routers of the service zones or source networks.
