Juniper Mist Edge Architecture

The components of the Juniper Mist Edge centralized architecture solution include the following:

  • Juniper Access Points

  • Juniper Mist Edge appliances

Figure 1 illustrates the architecture of Juniper Mist Edge and the configuration components.

The Juniper Mist Edge architecture includes the following configuration components:

  • Juniper Mist Edge—This component includes the hardware or virtual appliance. Within the Juniper Mist Edge configuration, you can configure the tunnel IP or hostname to which the access points (APs) form a tunnel.

  • Juniper Mist Edge cluster—You can configure cluster at the Org level and at the Site level.

    • Org Level —You can configure an Org level cluster, when APs from multiple sites are required to tunnel to a centralized location (DC).

      A cluster can have a single edge to multiple edges. Juniper Mist Edge must be a part of a cluster to actively terminate tunnels from the AP. Under normal operation, the members within a cluster are in active/active mode and load-balance all the AP tunnels.

    • Site Level —You can configure Juniper Mist Edge as a Site Edge, for deployments when :

      • You want the traffic to be tunneled at each site due to the underlying network constraints or security concerns

      • You have many sites with site-specific Juniper Mist Edge appliances and you want to reuse a WLAN template for ease of operation

      • Only APs from a single site need to be tunneled to a Juniper Mist Edge

  • Juniper Mist tunnels—The tunnel configuration decides the primary cluster and the secondary cluster for AP tunnel termination. The Juniper Mist tunnel object contains the attributes that determine the tunnel protocol, endpoints, tunneled VLANs, tunnel failover timers, automatic preemption, and other features.

  • Juniper Mist WLAN template—A WLAN template is a collection of WLAN policies, tunneling policies and WxLAN policies. Instead of repeating a given configuration across multiple service set identifiers (SSIDs), with WLAN templates you can set it once and then attach APs to the template to automatically inherit the setting.
