VRF-VXLAN VSD-domains are associated with R-VPLS services configured without a static route-target and vxlan VNI. VSD configures the dynamic route-target and VNI in the router VPLS service. Some considerations related to VRF-VXLAN domains are:
ip-route-advertisement, allow-ip-int-bind, as well as the VPRN evpn-tunnel commands are required for this type of VSD-domain. An example of configuration for a VRF-VXLAN association is shown below:

The VSD pushes a dynamic vxlan VNI and route-target that the router adds to the VPLS service. For the route-target, the system checks whether the VPLS service has a configured policy and pushes the route-target either in the service context or the vsi-import/export policies, as described in the section for L2-DOMAINs.
The following commands help show the association between the 7750 SR, 7450 ESS, and 7950 XRS router services and VSD-domains, as well as statistics and configuration errors sent/received to/from VSD.
