Cisco EVN is a successor solution that offers numerous advantages over traditional Multi-VRF technology:
● Simplified: To simplify campus virtual-network solutions, the Cisco EVN is designed with following three major components:
- Virtual network (VNET) trunk: The Cisco EVN solution reduces 98 to 99 percent of configuration complexities.
- Route replication: A simplified unicast and multicast route-leaking capability enables shared network and application services to virtual-network users. It replaces traditional Border Gateway Protocol (BGP)-based route-leaking mechanics.
- Routing context: Simplified and optimized virtual-network operation and troubleshooting are supported on a per-VRF basis.
● Scalable: Cisco EVN enables flexibility to scale up to 32 virtual network solutions - operationally 4x virtual-network scalability capacity over Multi-VRF technology.
● Interoperable: Cisco EVN provides network topology isolation based on an RFC-defined control plane; for example, Enhanced IGRP (EIGRP), Open Shortest Path First (OSPF), Multicast etc. The data-plane security and protection are maintained through industry-standard IEEE 802.1Q. In addition, the Cisco EVN‑supported system interoperates with peer Cisco EVN, Multi-VRF, and MPLS systems.
