TAILIEUCHUNG - Network Virtualization — Path Isolation Design Guide

Each partition is logically isolated from the others, and must provide the same services that are available in a traditional dedicated enterprise network. The end user experience should be as if connected to a dedicated network providing privacy, security, an independent set of policies, service level, and even routing decisions. At the same time, the network administrator can easily create and modify virtual work environments for various user groups, and adapt to changing business requirements adequately. The latter is possible because of the ability to create security zones that are governed by policies enforced centrally; these policies usually control (or. | Network Virtualization Path Isolation Design Guide Contents Introduction 3 Path Isolation Overview 6 Policy-Based Path Isolation 7 Control Plane-Based Path Isolation 8 Network Device Virtualization with VRF 9 Data Path Virtualization Single- and Multi-Hop Techniques 11 Path Isolation Initial Design Considerations 12 Path Isolation Using Distributed Access Control Lists 14 Connectivity Requirements 15 Configuration Details 15 Path Differentiation 17 High Availability Considerations 19 Challenges and Limitations of Distributed ACLs 19 Path Isolation over the WAN using Distributed ACLs 19 Path Isolation using VRF-Lite and GRE 21 Connectivity Requirements 21 Configuration Details 23 Using Point-to-Point GRE 23 Using mGRE Technology 32 MTU Considerations 37 Loopback IP Address Considerations 39 High Availability Considerations 43 Using VRF-Lite and GRE over the WAN 44 Americas Headquarters Cisco Systems Inc. 170 West Tasman Drive San Jose CA 95134-1706 USA 2007 Cisco Systems Inc.
