  • Patent number: 11405351
    Abstract: A method is provided in one example embodiment and includes detecting by a first network element at a first data center site a local connection of an endpoint identifier (“EID”), in which the EID was previously locally connected to a second network element at a second data center site and notifying a mapping server of the local connection of the EID to the first network element. The method further includes receiving from the mapping server identifying information for the second network element and communicating with the second network element using the identifying information to obtain service information for traffic associated with the EID. The method may also include applying a service identified by the service information to outgoing traffic from the EID as well as applying a service identified by the service information to incoming traffic for the EID.
