Switch the interconnection interface of the Fabric network device to the Ethernet L3 interface,

 configure the interface address for the underlay network,

configure the OSPF dynamic routing protocol for the Fabric network device,

 import the IP address of the Ethernet Layer 3 interface into the routing protocol.

Configure the same IP address for the loopback interfaces of VXLAN L3 GW1 and VXLAN L3 GW2.

Configure the same IP address for the same BD on VTEP IPVXLAN L3 GW1 and VXLAN L3 GW2 as the BDIF gateway address.

 Configure the DFS group to synchronize the ARP and MAC forwarding table information of the all-active gateway.
