Chapter 83 Configuring Easy Virtual Network
Configuring Easy Virtual Networks
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.
Step 3
Switch(config-vrf-list)# member vrf
name
Specifies an existing VRF as a member of a VRF list.
The VRF must be defined before it can be added to a list.
Step 4 Repeat Step 3 to add other VRFs to the
list. (Optional) If you want a trunk interface with one VRF, your list only
needs one VRF.
Step 5
Switch(config-vrf-list)#
exit-vrf-list
Exits VRF list configuration mode.
Step 6
Switch(config)# interface type
number
Configures an interface and enters interface configuration mode.
Step 7
Switch(config-if)# vnet trunk list
vrf list name
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.
Step 8
Switch(config-if)# ip address ip
address mask
Sets a primary IP address for the interface.
Step 9
Switch(config-if)# end
Ends the configuration session and returns to privileged EXEC mode.
Step 10
Switch# show vrf list [ vrf list
name ]
Displays information about the specified VRF list.
Command Purpose
Command Purpose
Step 1
Switch# configure terminal Enters global configuration mode.
Step 2
Switch(config)# interface type
number
Configures an interface type and enters interface configuration mode.
Step 3
Switch(config)# vrf forwarding vrf
name
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.
Note
Ensure that you are not on the trunk interface when you configure
an edge interface.
Step 4
Switch(config-if)# ip address ip
address mask
Sets a primary IP address for the interface.
Step 5
Switch(config-if)# end
Ends the configuration session and returns to privileged EXEC mode.
