Path Level Virtualization

VRF table separation is maintained across network paths, as shown in the following figure. Single-hop path
segmentation (hop by hop) is typically accomplished by using 802.1q VLANs, virtual path identifier/virtual
circuit identifier password (VPI/VCI PW), or easy virtual network (EVN). You can also use the Locator ID
Separation Protocol (LISP) in multihop mechanisms that include Multiprotocol Label Switching (MPLS) and
generic routing encapsulation (GRE) tunnels. LISP binds VRF instances to instance IDs (IIDs), and then these
IIDs are included in the LISP header to provide data plane (traffic flow) separation for single or multihop
needs.

LISP Virtualization at the Device Level

LISP implements Locator ID separation and thereby creates two namespaces; endpoint ID (EID) and routing
locator (RLOC). Either or both of these can be virtualized.
