Claim Text:
1. A method of providing an end user device associated with a user end point ID (“user EID”) in a first subnetwork access to one or more enterprise services in a second subnetwork, the method comprising: determining associated LISP (Locator/Identifier Separation Protocol) instance IDs for the user EID, wherein a LISP instance ID is associated with the one or more enterprise services; fetching identification information for the one or more enterprise services from a LISP map server; sending a service group join request on behalf of the user EID to the one or more enterprise services based on the identification information; allowing the end user device in the first subnetwork to access an enterprise service regardless of the end host or enterprise service location; and, updating a multicast tree, of a router, for a particular LISP instance ID to include the user EID joining the instance, wherein the multicast tree comprises other enterprise services and user EIDs that have already joined the particular LISP instance ID.
