Abstract
Systems and methods for advertising routing updates are disclosed. An example method includes forwarding a proposed routing update from a provider edge router to first and second customer edge routers when a route reflector determines that the proposed routing update having a first route target represents a desirable routing configuration for the provider edge router; and when the route reflector determines that the proposed routing update represents an undesirable routing configuration for the provider edge router: forwarding a first substitute routing update from the provider edge router to the first customer edge router different from the proposed routing update and including a second route target different from the first route target; and forwarding a second substitute routing update from the provider edge router to the second customer edge router different from the proposed routing update and including a third route target different from the first route target.
