Citrix ADC

VXLAN support for admin partitions

In a partitioned Citrix ADC appliance, similar to configuring a VLAN, you can configure a VXLAN in the default partition. After configuring a VXLAN, you can bind it to an administrative partition or if a VXLAN is extending a VLAN that is bound to a partition, the appliance binds the VXLAN to the partition under the same broadcast domain. It is applicable in unbinding a VLAN that unbinds a VXLAN from the partition.

For more information about how VXLAN works in a Citrix ADC appliance, see VXLAN.

Also, for more information on how VLAN works in a partitioned Citrix ADC appliance, see Admin Partitioning.

Points to remember before configuring a VXLAN

Remember the following points before you configure a VXLAN in a partitioned Citrix ADC appliance:

  • When you extend a VLAN over VXLAN, make sure VLAN is bound to the partition.
  • Only a partition administrator must configure the IP and dynamic routing for the VXAN in the administrative partition.

A shared VXLAN is not supported in a partitioned appliance and so a VXLAN cannot be tagged to a shared VLAN or you cannot make a VLAN a shared one when it is tagged to a VXLAN.

Supportable VXLAN configurations

Following are the supportable VXLAN configurations.

Extending VLAN over a VXLAN in the same broadcast domain

The following CLI steps help you to extend a VLAN over a VXLAN and the opposite way within the same broadcast domain.

  1. Add a VLAN in the default partition

     add vlan <id>
    
  2. Extend VLAN over a VXLAN within the same broadcast domain.

    add vxlan <vxlan id> –vlan <id>
    
  3. Configure a peer vtep to carry all BUM (broadcast unknown multicast) traffic.

    Note

    The vtep address can be a multicast address.

    add bridgetable -mac <mac_addr> -vxlan <positive_integer> -vtep <ip_addr> [-vni <positive_integer>][-deviceVlan <positive_integer>]
    
  4. Bind IP addresses to VXLAN.

    bind vxlan <id> [-srcIP <ip_addr>][-IPAddress <ip_addr|ipv6_addr|*> [<netmask>]]
    
  5. Bind VLAN to an administrative partition.

    bind partition <partition-id> -vxlan <id>
    
    add vlan 3000
    
    add vxlan 3000 –vlan 10
    
    add bridgetable –mac 00:00:00:00:00:00 –vxlan 3000 -vtep 10.102.58.8 –vni 11
    
    bind vxlan 3000 – srcIP 10.102.101.15
    
    bind partition p1 –vlan 10
