Creating an VTEP and NVE Interface

An NVE interface is the overlay interface that terminates VXLAN tunnels.
There is a one-on-one mapping between NVE interface configuration and the source interface. Source interface
used under a NVE cannot be reused.
You can create and configure an NVE (overlay) interface with the following:
Procedure
Step 1
Step 2
Step 3
Step 4
Step 5
Step 6
Step 7
Step 8
The following example shows how to create a VTEP / NVE interface:
switch# configure terminal
switch(config)# interface nve 1
switch(config-if)# source-interface loopback 10
switch(config-if)# member vni 7000 mcast-group 225.1.1.1
switch(config-if)# member vni 8000 mcast-group 226.1.1.1
switch# configure terminal
switch(config)# interface loopback 10
switch(config-if)# ip address 10.1.1.1/32
switch(config-if)# vrf member core
Command or Action
configure terminal
interface nve x
source-interface loopback
src-if
member vni vni [mcast-group
mcast-ip]
exit
interface loopback if-number
ip address address
vrf member core
Creating an VTEP and NVE Interface
Purpose
Enters global configuration mode.
Creates a VXLAN overlay interface that terminates VXLAN
tunnels.
Only 4 NVE interfaces are allowed on the switch.
Note
Range is from 1 to 4.
The source interface must be a loopback interface that is
configured on the switch with a valid /32 IP address. This
/32 IP address must be known by the transient devices in the
transport network and the remote VTEPs. This is
accomplished by advertising it through a dynamic routing
protocol in the transport network.
Associate VXLAN VNIs (Virtual Network Identifiers) with
the NVE interface.
Exits interface configuration mode.
Creates a loopback interface.
Assigns an ip address to the configured interface.
Creates a vrf member core in the interface.
