Virtual Extensible LAN (VXLAN) Tunnel

VXLAN is a simple tunneling mechanism that allows overlaying a Layer 2 (L2) network over a Layer 3 (L3) underlay with the use of any IP routing protocol. It uses MAC Address-in-User Datagram Protocol (MAC-in-UDP) encapsulation. For details about the VXLAN tunnels, refer to the "About Virtual Extensible LAN (VXLAN) Tunnels" section in the GigaVUE Fabric Management Guide.

Configure VXLAN Tunnel for Encapsulation

Create a VXLAN tunnel for encapsulation using the tunnel command, which has the following syntax:

tunnel alias <alias> encap vxlan
   comment <description>
   attach <ip-interface-name>

   ipdst <destination IP address>

   l4srcport <layer4 source leader in a bidirectional clock relationship (formerly master) port number>

   exit

The following table describes the arguments for the VXLAN tunnel for encapsulation using the tunnel command:

Argument

Description

tunnel alias <alias> encap vxlan

Specifies an alias for the VXLAN tunnel. The alias must be unique and can contain up to 128 characters. Aliases are case-sensitive.

For example:

(config) # tunnel alias <alias> encap vxlan

comment <description>

Specifies a description for the vxlan tunnel.

For example:

(config) tunnel alias <alias> encap vxlan) # comment <description>

attach <ip-interface-name>

Specifies the IP interface to which you have attached the circuit port you have configured on the device.

For example:

(config tunnel alias <alias> encap vxlan) # attach <ip-interface-name>
ipdst <destination IP address>

Specifies the IP address of the destination device of the tunnel.

For example:

(config tunnel alias <alias> encap l2gre) # ipdst <destination IP address>
l4srcport <layer4 source port number>

Specifies the layer 4 source port number

For example:

(config tunnel alias <alias> encap vxlan) # l4srcport <layer4 source port number>

exit

Exits the VXLAN tunnel configuration.

For example:

(config tunnel alias <alias> encap vxlan) # exit

Note:  Use this encap tunnel in the map configuration to encapsulate the traffic with VXLAN ID and send the traffic to the required destination device, where the traffic will be decapsulated.

Configure VXLAN Tunnel for Decapsulation

Create a VXLAN tunnel for decapsulation using the tunnel command, which has the following syntax:

tunnel alias <alias> decap vxlan
   comment <description>
   attach <ip-interface-name>
   exit

The following table describes the arguments for the VXLAN tunnel for decapsulation using the tunnel command:

Argument

Description

tunnel alias <alias> decap vxlan

Specifies an alias for the VXLAN tunnel. The alias must be unique and can contain up to 128 characters. Aliases are case-sensitive.

For example:

(config) # tunnel alias <alias> decap vxlan

comment <description>

Specifies a description for the VXLAN tunnel.

For example:

(config tunnel alias <alias> decap vxlan) # comment <description>

attach <ip-interface-name>

Specifies the IP interface to which you have attached the circuit port you have configured on the device.

For example:

(config tunnel alias <alias> decap vxlan) # attach <ip-interface-name>

exit

Exits the VXLAN tunnel configuration.

For example:

(config tunnel alias <alias> decap vxlan) # exit

Note:  Use this decap tunnel in the map configuration to decapsulate the traffic with VXLAN tunnel and send the traffic to the required tool ports of the map.

Configure VXLAN Group

Create a VXLAN group using the tunnel command, which has the following syntax:

tunnel vxlan [box-id <id|all>] vxlan-group alias <vxlan-group-name>
   add <vxlan-id-list>
   comment <description>
   delete <vxlan-id-list>
   exit

The following table describes the arguments for configuring the VXLAN group using the tunnel command:

Argument

Description

tunnel vxlan [box-id <id|all>] vxlan-group alias<vxlan-group-name>

Specifies the box identifier in which the VXLAN IDs will be added. Also, specifies an alias for the VXLAN group. The alias must be unique and can contain up to 128 characters. Aliases are case-sensitive.

For example:

(config) # [no] tunnel vxlan [box-id <id|all>] vxlan-group alias <vxlan-group-name>

add <vxlan-id-list>

Adds the VXLAN IDs for the device. The range is 1 to 4294967295.

For example:

(config tunnel vxlan [box-id <id|all>] vxlan-group alias <vxlan-group-name>) #add <vxlan-id-list>

comment <description>

Specifies the description for the VXLAN group.

For example:

(config tunnel vxlan [box-id <id|all>] vxlan-group alias <vxlan-group-name>) #comment <description>

delete <vxlan-id-list>

Deletes the specific VXLAN group.

For example:

(config tunnel vxlan [box-id <id|all>] vxlan-group alias <vxlan-group-name>) #delete <vxlan-id-list>

exit

Exits the VXLAN group configuration.

For example:

(config tunnel vxlan [box-id <id|all>] vxlan-group alias <vxlan-group-name>) #exit

Configure VXLAN ID

The VXLAN ID that you have added in the VXLAN group created for a specific device must be configured either at the chassis-level or at the network port-level. The ID that you configure for the network port overrides the ID configured for the chassis. The VXLAN IDs help to identify the respective tunnels.

Configure VXLAN ID for a chassis using the tunnel command, which has the following syntax:

tunnel vxlan box-id <id> global-encap-id <vxlan ID>
   exit

The following table describes the arguments for configuring the VXLAN ID at the chassis-level using the tunnel command:

Argument

Description

tunnel vxlan box-id <id> global-encap-id <vxlan ID>

Specifies the box identifier for which the VXLAN ID will be added. Also, specifies the VXLAN ID that will be configured for the chassis.

For example:

(config) # tunnel vxlan box-id <id> global-encap-id <vxlan ID>

exit

Exits the VXLAN ID configuration.

For example:

(config) # tunnel vxlan box-id <id> global-encap-id <l2gre ID> #exit

Note:  To configure VXLAN ID for a network port, refer toport.
