Abstract: In one embodiment, a method includes activating a first network apparatus within a network and determining, by the first network apparatus, that a Scalable Group Tag (SGT) Exchange Protocol (SXP) is configured on the first network apparatus. The method also includes costing out the first network apparatus in response to determining that the SXP is configured on the first network apparatus. Costing out the first network apparatus prevents Internet Protocol (IP) traffic from flowing through the first network apparatus. The method further includes receiving, by the first network apparatus, IP-to-SGT bindings from an SXP speaker, receiving an end-of-exchange message from the SXP speaker, and costing in the first network apparatus in response to receiving the end-of-exchange message. Costing in the first network apparatus allows the IP traffic to flow through the first network apparatus.
