9 Managing EVI
Ethernet Virtual Interconnect (EVI) is a MAC-in-IP technology that provides Layer 2 connectivity between
distant Layer 2 network sites across an IP routed network.
EVI links between edge devices at different sites form an EVI network, as shown in
Figure 19 .

EVI deployment and maintenance
You can use VFM to deploy EVI networks and maintain basic EVI parameters. To tune EVI ISIS and
network optimization parameters such as ARP flooding suppression, you must use the CLI of each EVI
device.
This document describes EVI management from the following aspects:
• Basic device management
• Device-specific EVI management
• Unified EVI service management
• EVI link monitoring
For more information about EVI concepts and configuring EVI from the CLI, see the EVI configuration
guide for the managed devices.
