Cisco APIC Layer 3 Networking Configuration Guide, Release 6.2(x)

Configure a VXLAN site ID

Updated: April 17, 2026

Want to summarize with AI?

Assign the unique VXLAN site ID required to configure a border gateway set policy.

Use this procedure to configure a VXLAN site ID in Cisco APIC Release 6.1(2) or later.

Beginning with Cisco APIC Release 6.1(2), you must configure a VXLAN site ID before you configure a border gateway set policy.

Note

If you configured the ACI border gateway feature in Cisco APIC Release 6.1(1) and upgrade to Cisco APIC Release 6.1(2) without creating a VXLAN site ID, Cisco APIC generates a fault for all stretched VRFs and bridge domains.

Procedure

From the top menu bar, choose Tenants > infra > Policies > VXLAN Gateway > VXLAN Site.
Right-click VXLAN Site and choose Create VXLAN Site.

The Create VXLAN Site window appears.
In the Name field, enter a name for the VXLAN site.
In the ID field, enter a unique ID for the VXLAN site.
Optional: In the Description field, enter a description of the VXLAN site.
Click Submit.

The VXLAN site is created with the specified ID. You can now configure the border gateway set policy.
