Network Settings

Explore the options that you can configure when creating a network.

Finding the Network Page

From the left menu, click Organization > WAN > Networks.

Note: For step-by-step instructions, see WAN Assurance Configuration Overview.

Configuration Options

Table 1: Network Options
Fields Description
Name Enter a unique name for the network. The name can contain alphanumeric characters, underscores, and hyphens, and must be less than 32 characters long.
Subnet IP Address Enter the network IP address. You can use absolute values (example: 192.0.2.0) or variables. Example: {{SPOKE_LAN1_PFX}}.0. For more information, see Use Site Variables to Streamline Configuration.
Prefix Length Enter the length of the address prefix, from 0 through 32. You can also use variables for the prefix length. Example: {{PFX1}}
VLAN ID

Enter the VLAN ID that is associated with the network.

If your device is using an untagged interface, you should use 1 as the VLAN ID instead of the variable.
Access to Mist Cloud

Check this option to allow other devices within the defined network to connect to the Mist cloud for management through the Session Smart Router.

We recommend this option if you intend to have Juniper switches or Juniper APs on this network. WAN Edge devices have built-in policies for connecting to Mist cloud services using WAN interfaces. By enabling this option, you permit the network to use these built-in policies.

Use case example: Management LAN networks for Mist-managed devices.
Advertise to the Overlay

Select this option to advertise the network to the hub devices through the overlay tunnels. By using this feature, you gain the ability to advertise over the SD-WAN, enabling enhanced control and reachability.

You can enable or disable these additional options:

  • Advertise to Other Spokes—This option leverages BGP community strings to allow the route to be sent to other spokes via the hub as a BGP route reflector. The WAN Edge device will originate a static route out to the attached networks.

    You might not need this option in these situations:

    • If you already have an aggregate route from the hub, you likely do not need to make this route visible to all spokes.

    • If you want the network to advertise the prefix only to hubs (not to other spokes), disable this option.

  • Advertise to Hub LAN BGP Neighbor—This option leverages BGP community strings to allow this route to be advertised into BGP at the edge of the SSR fabric (hub LAN, spoke LAN, or spoke SSE BGP). The WAN Edge device will originate a static route out to the attached networks.
  • Advertise to Hub LAN OSPF Neighbor (SRX Only)—This option leverages OSPF to advertise the network prefix to any LAN OSPF neighbor at the hub.
  • Override Prefix to Advertise—Enable this option when the prefix to advertise to the hubs is different from the original network. For example, you might use this option when enabling NAT. If you select this option, also enter the IP Address and Prefix Length.
Summarize

Select from the following route summarization options:

  • Hub Overlay Summarization—Enable the network to summarize the network prefix advertised to the overlay. For example: Juniper Mist portal can summarize 192.168.1.0/24 to 192.168.0.0/16. This feature limits the number of BGP updates received by a hub from each spoke and sent by the hub back to all the other spokes.
  • Hub LAN BGP Summarization—Enable the network to summarize the network prefix advertised to the LAN BGP neighbor. For example: Juniper Mist portal can summarize 192.168.1.0/24 to 192.168.0.0/16.
  • Hub LAN OSPF Summarization (SRX Only)—Enable the network to summarize the network prefix advertised to the LAN OSPF neighbor. For example: Juniper Mist portal can summarize 192.168.1.0/24 to 192.168.0.0/16.
  • Route Summarization—Summarize local routes toward overlay. You can specify the IP addresses and prefix length of the summarized routes. Session Smart Routers support summarization when the network is attached to the spoke only.

Networks not directly attached

(SSR Only)

Select the networks that are not directly connected networks that arrive on this network assigned to a LAN.

For example, enable this option for indirectly connected prefixes behind a router on a LAN segment. You'd also use this option in cases where there are geo-redundant hubs that could potentially provide access to the same core network space.
Users

Additional networks or users. Example: remote networks or users connected to the main network.

Click Add User and

then enter the Name and IP Prefixes.
Static NAT

Perform a one-to-one static mapping of the original private host source address to a public source address.

Click the Add Static NAT option and enter the Name , Internal IP, External IP and select the option to apply to outgoing traffic on the Underlay or Overlay.

For SRX, also enter the WAN Name.
Destination NAT

Translate the destination IP address of a packet.

Click the Add Destination NAT option and enter the Name , Internal IP, Internal Port, External IP, External Port and select the option to apply to outgoing traffic on the Underlay or Overlay.

SRX Only: also enter the WAN Name.
