Configuring EVN Edge Interfaces

Perform this task to configure an edge interface, which connects a user device to a virtual network.
Traffic carried over an edge interface is untagged. The edge interface determines which virtual network
the received traffic belongs to. Each edge interface is mapped to only one virtual network.

Verifying EVN Configuration
Enter the following commands to verify your configuration. All the existing VRF show commands are
supported in virtual networks. If a device has a mix of VRFs and virtual networks, the various show vrf
commands will include both VRFs and virtual networks in the output.

Purpose
Specifies an existing VRF as a member of a VRF list.
The VRF must be defined before it can be added to a list.
(Optional) If you want a trunk interface with one VRF, your list only
needs one VRF.
Exits VRF list configuration mode.
Configures an interface and enters interface configuration mode.
Defines a trunk interface and enables the VRFs that are in the VRF list.
Use the vrf list name you defined earlier in this task.
Sets a primary IP address for the interface.
Ends the configuration session and returns to privileged EXEC mode.
Displays information about the specified VRF list.
Purpose
Enters global configuration mode.
Configures an interface type and enters interface configuration mode.
Defines an edge interface and determines the VRF to which the incoming
traffic belongs.
The vrf name must already be defined using the vrf definition command.
Ensure that you are not on the trunk interface when you configure
Note
an edge interface.
Sets a primary IP address for the interface.
Ends the configuration session and returns to privileged EXEC mode.
