Note: In this deployment example, anycast gateways are used on Leafs 1a, 1b, 2a, and 2b. 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.
6.4 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.

Note: The remaining leaf switches are configured in the same manner. VRF tenant1 is created on all six leaf
switches.
