Test Objectives

Test Goals

The testing for this JVD was performed with the following goals in mind:

  • This solution was tested with two major fabric types:
    • EVPN multihomed fabric with a Layer 2 transport VLAN attached to WAN router. The approach for this fabric is to use static IPs from VGA as relay gateway IPs.
    • IP Clos 5-stage fabric with BGP protocol attached to WAN router. Physical service blocks are optional but recommended. The approach for this fabric is to use extra loopback IPs as relay gateway IPs.
  • The two major DHCP server integration types must be tested with each of the two fabric types:
    • Local attach to the fabric through the service block function:
      • Test the DHCP server as part of the same VRF which does not involve the WAN router.
      • Test the DHCP server in a different VRF which does involve the WAN router for hair-pinning of traffic.
    • Remote attachment of the DHCP server outside of the fabric. In this case, you must ensure that no form of NAT between the fabric WAN router and the DHCP server is performed.
  • All tests with the two fabric and integration types must happen with the two major DHCP server flavours we test for this solution from different third-party vendors:
    • Microsoft 2022 DHCP Server (as VM).
    • Linux KEA DHCP server (as VM).
  • A client must get a DHCP lease as:
    • New MAC address with the full cycle of (Discover, Offer, Request and Ack).
    • Lease renew (Request and Ack only).
  • Special client situations must be tested such as:
    • Getting a DHCP release from clients attached to a service block function. This will emulate the behaviour of a Juniper Mist Edge device integrated into the fabric managing Wi-Fi clients at scale.
    • Wi-Fi roaming to a new VLAN. The MAC address of the client needs to be the same but when it connects to a new port, a different VLAN then needs to be assigned. This will simulate a roaming Wi-Fi client between buildings and SSIDs.
Note:

Review the separate Test Report for more detailed information.

Test Non-Goals

The testing for this JVD was not performed, for various reasons, on the following items:

  • Testing with many different third-party DHCP servers. Our testing focuses on two major products seen in the field:
    • Microsoft DHCP server in Windows 2022 as a commercial product.
    • Linux-based KEA DHCP server as free and professional alternative from the Internet Systems Consortium.
  • Redundancy of the DHCP server itself will not be tested. An internal lease sharing Database and how to set it up is subject to the customer DHCP server installation.
  • Testing with CRB or ERB fabric designs was not performed. With the tests on EVPN multihoming and IP Clos, the major differences are captured already.
  • Testing with two integrated WAN routers. This was already tested as part of the JVDE for WAN router integration.
  • Microsoft DHCP server in Windows 2022 was not integrated into an AD, nor was it responsible for DNS management. This is subject to individual customer integration.
