The solution described in Anycast Redundant Solution for Dual BGP Instance Services is also supported in multi-instance EVPN-VXLAN VPLS services.
The following CLI example output shows the configuration of DCGW-1 and DCGW-2 in Figure 1 where VPLS 500 is a multi-instance EVPN-VXLAN service and BGP instance 2 is associated with VXLAN instead of MPLS.
Different default-route-tags are used in BGP instance 1 and instance 2, so that in the export route policies, DC routes are not advertised to the WAN, and WAN routes are not advertised to the DC, respectively.
