Hierarchy Level


On ACX7100-32C, ACX7100-48L, and ACX7024 devices, you can use either an IPv4 or IPv6 underlay for a VXLAN configuration. To use an IPv6 underlay, enable the vxlan-extended system profile.

Before you enable the vxlan-extended system profile, remove any existing VXLAN configurations. After you enable the vxlan-extended statement, the packet forwarding engine (PFE) reboots. After the PFE comes back up, you can configure an underlay and overlay for the IPv6 VXLAN underlay. Once you have configured the IPv6 VXLAN underlay and overlay, your VXLAN deployment will be using an IPv6 underlay.

If you want to use an IPv4 underlay, enable the default system profile and remove the IPv6 VXLAN underlay configuration.

To enable the default system profile, issue the delete system packet-forwarding-options system-profile vxlan-extended command. Apply your underlay and overlay configuration for your IPv4 VXLAN underlay configuration. After the PFE reboots, your VXLAN deployment will be using an IPv4 underlay.
