● VLT peer routing is not supported in a virtual network. A packet destined to the virtual-network peer MAC address L2
switches instead of IP routes. To achieve active-active peer routing in a virtual network, configure the same virtual anycast
gateway IP and MAC addresses on both VTEP VLT peers and use the anycast IP as the default gateway on the VMs.
● Virtual Router Redundancy Protocol (VRRP) is not supported on a virtual-network interface. Configure the virtual anycast
gateway IP address to share a single gateway IP address on both VTEP VLT peers and use the anycast IP as default gateway
on the VMs.
● Internet Group Management Protocol (IGMP) and Protocol-Independent Multicast (PIM) are not supported on a virtual-
network interface.
● IP routing of incoming VXLAN encapsulated traffic in the overlay after VXLAN termination is not supported.
The following tables show how to use anycast gateway IP and MAC addresses in a data center with three virtual networks and
multiple VTEPs:
● Globally configure an anycast MAC address for all VTEPs in all virtual networks. For example, if you use three VTEP switches
in three virtual networks:

● Configure a unique IP address on the virtual-network interface on each VTEP across all virtual networks. Configure the same
anycast gateway IP address on all VTEPs in a virtual-network subnet. For example:
