This section shows a configuration example for three PEs in a Data Center, all the following assumptions are considered:
PE-1 is a Data Center Network Virtualization Edge device (NVE) where service VPLS 2000 is configured.
PE-2 and PE-3 are redundant Data Center Gateways providing Layer 2 connectivity to the WAN for service VPLS 2000.
DC PE-1 configuration for service VPLS 2000
DC PE-2 and PE-3 configuration with SAPs at the WAN side (advertisement of all macs and unknown-mac-route):
vpls 2000 name "2000" customer 1 create
vxlan instance 1 vni 2000 create
exit
bgp
route-distinguisher 65001:2000
route-target export target:65000:2000 import target:65000:2000
exit
bgp-evpn
unknown-mac-route
vxlan bgp 1 vxlan-instance 1

DC PE-2 and PE-3 configuration with BGP-AD spoke-SDPs at the WAN side (mac-advertisement disable, only unknown-mac-route advertised):
