I am reading the Cisco doc "VXLAN Network with MP-BGP EVPN Control Plane"
I know the VLAN ID is locally significant in the context of VXLAN and multiple VXLANs can be mapped to a single VLAN.
But on page 12, from the configuration as the attached:
Looks like each VXLAN has to map to 1 VLAN especially from Distributed IP Anycast Gateway configuration point of view.
Does this mean that we can only have 4096 VXLAN on each VTEP device?
If not, how we can map multiple VXLANs to 1 VXLAN?
In addtion, why we need this VXlan_to_vlan mapping? If we temporarily put the integraition with legacy vlan-based network/physical server aside, does a purely VXLAN overlay network not work?
