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.

Abstract: Aspects of the embodiments are directed to systems, methods, and computer program products to program, via a northbound interface, a mapping between an endpoint identifier (EID) and a routing locator (RLOC) directly into a mapping database at a mapping system; receive, from a first tunneling router associated with a first virtual network, a mapping request to a second virtual network, the first router compliant with a Locator/ID Separation Protocol, the mapping request comprising an EID tuple that includes a source identifier and a destination identifier; identify an RLOC based, at least in part, on the destination identifier of the EID tuple from the mapping database; and transmit the RLOC to the first tunneling router implementing an high level policy that has been dynamically resolved into a state of the mapping database.
