Example: Multi-tenant Networks The complexities we have to deal with today... Compute Access Data Center Core Campus Core Distribution Layer Blue Departmental Access Layer Application with IGP configured for routing L3 Core with VRF & MBGP Green Departmental User s with IGP configured for routing VRF Configuration VRF to VSN Mapping Will be simplified by... VRFs traffic separation which is maintained through VSN Layer 3 VRF extension across the Virtual Services Fabric Use of shared services becomes simple and efficient 2011 Avaya Inc.
