# Common Connectivity Scenarios

> This help topic describes common connectivity scenarios when using Megaport.

This topic describes eight common scenarios delivering different levels of protection at the physical layer connecting to Megaport SDN.

<Tabs>
  <Tab title="Scenario 1">
    Customer edge device stack (switch/router/firewall) at a single Megaport Point of Presence (PoP) with a single cross connect connecting to a single Port.

    **Protection at the Physical Layer**

    | Component       | Protection |
    | --------------- | ---------- |
    | Megaport PoP    | N/A        |
