vxlan-stitching

Syntax

Hierarchy Level

Description

You must configure vxlan-stitching on ACX devices to support Virtual Extensible LAN (VXLAN) data center interconnect (DCI) stitching features.

Note:

The PFE will restart once this statement is applied.

Options

control-word

Enable this option on an ACX device operating as a DCI gateway (GW) when both of the following are true:

  • Your MPLS network is using Ethernet VPN (EVPN-MPLS) for the overlay fabric.

  • Your ACX DCI GW's peer device is using control-word. For example, you may be connecting across the DCI to a PTX, which only supports control-word.

Consider the following when configuring control-word support.

  • control-word support is disabled by default on ACX devices. Only enable this option when control-word support is required.

  • control-word support is enabled by default in MAC-VRF routing-instances.

  • In EVPN-VXLAN to EVPN-MPLS networks, when the peer GW doesn't support control-word, configure the vxlan-stitching knob as described, and configure the no-control-word option in the [edit routing-instances instance-name protocols evpn] hierarchy.

  • In EVPN-VXLAN to EVPN-MPLS networks, when the peer GW does support control-word, configure the control-word option in the [edit system packet-forwarding-options system-profile vxlan-stitching hierarchy.

Default

Stitching features are disabled.
