This is configured with the ip virtual-router mac-address command above. Anycast gateways are not used on Leaf3a or Leaf3b since servers are not directly connected to them. VLAN configuration 1. Create VLANs 1614, 1615, and 1616 and map them to their corresponding virtual networks created in the preceding section. 2. Create VLAN 4000 and give it an IP address. This address is used for iBGP adjacency between the leaf switches. This is considered a best practice and ensures that routes are shared between VLT peers in case one becomes unavailable. The IP addresses are from Table 1. VLAN configuration Leaf1a interface vlan1614 virtual-network 1614 no shutdown Leaf1b interface vlan1614 virtual-network 1614 no shutdown interface vlan1615 virtual-network 1615 no shutdown interface vlan1615 virtual-network 1615 no shutdown interface vlan1616 virtual-network 1616 no shutdown interface vlan1616 virtual-network 1616 no shutdown interface vlan4000 ip address 192.168.3.0/31 interface vlan4000 ip address 192.168.3.1/31 Note: The remaining leaf switches are configured in the same manner. VRF tenant1 is created on all six leaf switches. 24 Dell EMC Networking Virtualization Overlay with BGP EVPN
