SD-LAN Use Cases

 

You can implement the Contrail SD-LAN solution in a branch and campus network to mange your switches and access points as follows:

  • EX Behind an Internet Gateway: In this implementation, you can manage multiple EX Series switches by connecting them to CSO through an Internet Gateway; see Figure 1.

    The Internet gateway device can be a Juniper Networks device or a third-party device.

  • EX behind an SD-WAN CPE: In this implementation, you can manage an EX Series switch by connecting it to CSO through an SD-WAN CPE; see Figure 2.

  • EX behind a next-generation firewall: In this implementation, you can manage an EX Series switch with by connecting it to CSO through a next-generation firewall; see Figure 2.

You can manage multiple switches by using CSO, when the switches are connected to CSO through a CPE or a next-generation firewall as shown in Figure 3.

However, in this implementation, you must manage the connectivity and configuration between the switches and the CPE or next-generation firewall either by using configuration templates provided by CSO or manually; see the Configure an EX Series Switch chapter in this guide for details.
