Campus and Branch LAN Design

You are designing a network for a small campus with Mist. You have two Junos switches that support EVPN-VXLAN core devices and two Junos access switches that do not support EVPN-VXLAN.

Which campus design is available with these devices?

  • A EVPN Multihoming
  • B Campus Fabric core-distribution
  • C Campus Fabric 3-stage IP Clos
  • D Campus Fabric 5-stage IP Clos
Explanation

EVPN Multihoming supports a collapsed-core design in which EVPN-VXLAN runs on the core devices, while standalone Junos access switches that do not support EVPN-VXLAN can attach through standard LACP. This design is intended to preserve an existing access layer.
