According to the Juniper documentation1, EVPN route Type-3 is used to advertise the IP address of the VTEP and the VNIs that it supports. This allows the VTEPs to discover each other and form VXLAN tunnels for the VNIs that they have in common. EVPN route Type-2 is used to advertise the MAC and IP addresses of the hosts connected to the VTEPs. This allows the VTEPs to learn the MAC-to-IP bindings and the MAC-to-VTEP mappings for the hosts in the same VNI. Therefore, these two types of VXLAN tunnels will be automatically created by the EVPN control plane when using Juniper Apstra with the ERB design blueprint and two virtual networks in a common routing zone. References: Example: Configure an EVPN-VXLAN Centrally-Routed Bridging Fabric
