Create Secure Mesh Site v2

• In Multi-Cloud Network Connect service, navigate to Manage > Site Management > Secure Mesh Sites v2.

• Select Add Secure Mesh Site to open the configuration form.

• In the Metadata section, enter a name for the Site.

• Optionally, select labels and add a description.

• From the Provider Name menu, select the infrastructure provider from the options available. Refer to provider-specific documentation links below to bring up infrastructure in that provider:

  • VMware
  • KVM
  • AWS
  • Azure
  • GCP
  • OCI
  • Nutanix
  • OpenStack

• For the Orchestration Mode menu option, select Not Managed By F5XC. With this option, Distributed Cloud Services will not automate any infrastructure provisioning (like node bring up). You are expected to bring up infrastructure using the provider-specific manual workflows or using the provider specific automation tools, like Terraform.

• For High Availability, choose an option. If it is Disabled, the CE Site will only support one node. If it is Enabled, the CE Site requires three nodes. Additional nodes can only be added to CE sites when HA is Enabled.

Important: The HA mode cannot be changed after the CE Site is created.

Use the following steps to configure the regional edge (RE) Site settings in the Regional Edge section. Your CE Site will connect to the RE Site for registration purposes.

Note: The configuration options in this section are set to standard default values. Therefore, it may not be necessary to customize any of the options unless you need customization only for advanced deployments.

• From the Regional Edge Selection menu, select the RE geography to use. The default option is use the geographically-closest RE Site to where you are deploying your CE Site.

• Optionally, select the Site-to-Site tunnel encryption type from the Tunnel Type menu. The default option is IPsec/SSL. When IPsec/SSL is used, IPsec takes priority.

• Optionally, configure the timeout value for Site tunneling from the Tunnel Dead Timeout (msec) menu. The default option is zero (0) milliseconds.

• Optionally, enable the offline survivability feature from the Offline Survivability Mode menu. For more information, see the Manage Site Offline Survivability guide.

Use the following steps to configure the CE Site networking settings in the Site Networking section.

Note: The configuration options in this section are set to standard default values. Therefore, it may not be necessary to customize any of the options unless you need customization only for advanced deployments.

• Site Local Outside Network (SLO) is used to connect the CE node with the F5 Distributed Cloud Regional Edges (REs). It can also work as a public/WAN network. This network typically requires connectivity to the Internet (see note below for exception). If a custom DNS server or static routes need to be added into this network, then from the Site Local Outside Network menu, choose Configure Site Local Outside Network. Then click View Configuration. Here you can add custom static routes, common VIP for load balancers (this can be overridden on a per load balancer basis in the Advertisement Policy), or DNS servers for the SLO network.

Note: The CE Site can be connected to a private underlay that connects with F5 Distributed Cloud Regional Edges (REs) in which case the SLO need not have Internet-bound connectivity. Connectivity to the REs will use this private underlay.

• Site Local Inside Network (SLI) represents the internal network (LAN). If a custom DNS server or static routes need to be added into this network, then from the Site Local Inside Network menu, choose Configure Site Local Inside Network. Then click View Configuration. Here you can add custom static routes, common VIP for load balancers (this can be overridden on a per load balancer basis in the Advertisement Policy), or DNS servers for the SLI network.

Note: Site Local Inside is an optional network. Consider using Network Segments from Multi-Cloud Network Connect > Networking > Segments for internal networks. Network segments are flexible and can be used to keep networks isolated within an environment. In other words, they are restricted to a single CE Site or can be also used for seamless extension of networks across multiple hybrid/multi-cloud environments (across multiple CE sites).

• To enable virtual IP address (VIP) redundancy when operating load balancers advertised on a CE in L2 adjacency mode: From the Load Balancer Settings section, select Enable VRRP for VIP(s) from the VRRP Mode setting.

Use the following steps to configure the CE Site networking settings in the Site To Site Connectivity section.

Note: The configuration options in this section are set to standard default values. Therefore, it may not be necessary to customize any of the options unless you need customization only for advanced deployments.

• To connect the Site to other sites using the SLO network, from the Connect using SLO Local VRF menu, select an option:

  • Site Mesh Group: This option connects your Site to other Sites in a mesh network. You can connect using a public IP or a private IP. For more information, see the Site Mesh Group guide.

  • Member of DC Cluster Group: This option places your Site within a Direct Connect (DC) Cluster Group. For more information, see the Configure DC Cluster Group guide.

• To connect the Site to other sites using the SLI network, from the Connect using SLI Local VRF menu, select Member of DC Cluster Group. For more information, see the Configure DC Cluster Group guide.

Use the following steps to configure the CE Site networking security settings in the Network Security section.

Note: The configuration options in this section are set to standard default values. Therefore, it may not be necessary to customize any of the options unless you need customization only for advanced deployments.

• From the Network Firewall menu, choose to enable an enhanced firewall. Select the firewall from the drop-down menu. Use Add Item to add more than one firewall. For more information, see the Network Firewall guide.

• From the Forward Proxy menu, choose to enable a forward proxy. Select the policy from the drop-down menu. Use b to add more than one policy. The network traffic will be processed based on the order set. For more information, see the Forward Proxy Policies guide.

Use the following steps to configure the CE Site performance mode in the Services & Resources section.

Note: The configuration option in this section is set to standard default values. Therefore, it may not be necessary to customize it unless you need customization only for advanced deployments.

• In the Services & Resources section, from the Performance Mode menu, select an option:

  • L7 Enhanced: This option optimizes the Site for Layer 7 traffic processing and is the default option.

  • L3 Enhanced: This option optimizes the Site for Layer 3 traffic processing. When chosen, this CE Site will not provide any L7 functionality, such as load balancing. If you are using L3 Enhanced mode, select whether to use this feature with or without jumbo frames.

Important: If L3 Enhanced mode is not enabled on all CE sites in a Site Mesh Group, the MTU configured on the Site-to-Site tunnel interfaces will not be consistent. Therefore, it is recommended to enable L3-focused performance mode on all sites participating in a Site Mesh Group.

Enable the Show Advanced Fields option.

Click Save and Exit to complete creating the Site. The Status field for the Site object displays Validation in progress. After validation, the field displays Validation Succeeded.

Important: There are certain settings that cannot be changed after the CE Site is created. Make sure that all settings for your CE Site are configured as required before clicking Save and Exit to avoid re-creating the CE Site and re-deploying the CE nodes.
