source (NVE interface view)

Function

The source command sets an IP address for the source VTEP.

The undo source command deletes the IP address configured for the source VTEP.

Format

source ip-address

undo source [ ip-address ]

Parameters

Parameter	Description	Value
ip-address	Specifies the IP address of the source VTEP.	The IP address is in dotted decimal notation.

Views

NVE interface view

Default Level

2: Configuration level

Usage Guidelines

By default, VTEPs do not have IP addresses.

Application Scenarios

VTEPs are ends of VXLAN tunnels. They are encapsulated in NVEs to encapsulate and decapsulate VXLAN packets.

When configuring a VXLAN tunnel, you must run the source command to configure an IP address for the source VTEP. The IP address of the source VTEP is the source IP address of a VXLAN packet. The IP address of the peer VTEP is the destination IP address of a VXLAN packet. A pair of VTEP addresses identifies a VXLAN tunnel.

Precautions

The IP address of the source VTEP can be the address of a physical interface or the loopback interface. Using the loopback interface address is recommended. Do not use the IP address of a virtual system. Otherwise, the tunnel cannot be established.

Example

# Configure the IP address of the source VTEP in the NVE interface view.

<sysname> system-view
[sysname] interface Nve 1
[sysname-Nve1] source 192.168.1.2

# Delete the IP address of the source VTEP in the NVE interface view.

<sysname> system-view
[sysname] interface Nve 1
[sysname-Nve1] undo source 192.168.1.2

# Delete the IP address of the source VTEP without specifying the IP address in the NVE interface view.

<sysname> system-view
[sysname] interface Nve 1
[sysname-Nve1] undo source
