Secure Mesh Site v2 deployment guide
Ce contenu n’est pas encore disponible dans votre langue.
F5 Distributed Cloud (XC) Secure Mesh Site v2 (SMSv2) connects Customer Edge (CE) nodes to the control plane and application networks. Use this guide to separate site configuration, node registration, realized interfaces, and working traffic. A successful Terraform apply proves only the operations that its graph actually checks.
Topology and terminology
Section titled “Topology and terminology”| Term | Operator meaning |
|---|---|
| Site | The XC configuration and lifecycle boundary; it is not the virtual machine. |
| Single-node site | One node with high availability (HA) disabled. MCN’s AWS path uses three independent sites. |
| Three-node site | One HA cluster. Three independent sites do not become a cluster by sharing a virtual-site selector. |
| Site Local Outside (SLO) | Required outside/control-plane network. A cloud NIC called management can still be SLO. |
| Site Local Inside (SLI) | Inside application routing context; keep it distinct from the physical transport of an encapsulated tunnel. |
| Management network | A separate management interface/virtual routing and forwarding (VRF) context, supported for single-node sites, not three-node clusters. |
| Virtual site | A selector over sites. Verify its actual selectees before relying on placement. |
F5 provisions SMSv2 with one control node or three HA control nodes. Supported worker nodes can be added after an HA site is online. Nodes require the same interface count and corresponding interfaces in the same network/VRF; HA is a creation decision. See the F5 creation guide and SMSv2 FAQ. Use the interface model for interface ordering and management constraints, and HA comparison for clustering versus independent sites.
Explicit and discovered nodes
Section titled “Explicit and discovered nodes”Provider v8 accepts omitted or empty AWS not_managed node lists for registration-time
discovery. Explicit nodes declare their hostname and interfaces. Neither mode proves
that a physical interface has appeared or that a route is installed.
Correlate actual site ownership, node, media access control (MAC) address, role, and maximum transmission unit (MTU). Guest device names are observations from the selected image and virtual hardware. Discover the realized XC interface object; constructing its likely name is not health evidence. The provider parity record describes discovery validation and the limits of structural parity.
rSeries is excluded as a verified platform removal: the observed API response was
Rseries provider is not supported for SecureMeshSite. This is evidence of rejection,
not an inference from deprecation. Other platforms require their own acceptance evidence.
Tested baseline
Section titled “Tested baseline”Baseline: the release acceptance merged on 2026-09-08 UTC. Earlier Azure observations retain their original dates. These are test results, not a promise for every image or tenant.
| Surface | Evidence and limit |
|---|---|
| Release identity | Provider v8.0.0, enriched API v6.1.2; immutable release chain in MCN PR #1103. |
| Independent parity | 1,699 legacy paths classified; zero unclassified paths and zero generated-provider gaps. This inventory alone does not establish runtime parity on every platform. Parity record. |
| AWS topology | 3 sites, 6 physical interfaces, 6 Connect peers, 12 established Border Gateway Protocol (BGP) sessions. One CE outage left 8 sessions; recovery restored 12. |
| AWS traffic | 849 samples, no retry-window virtual IP (VIP) failures, 26 separately counted raw transport transients, zero origin-control failures. This does not mean every first attempt succeeded. |
| AWS lifecycle | 3 completed serial software/operating-system upgrades and a final refresh-enabled no-change plan. |
| Azure | Observations through 2026-08-08 cover registration, routes, and traffic. Final provider-v8 acceptance did not mutate or re-prove Azure end-to-end. |
AWS results above come from PR #1103. Azure evidence remains in verification and the dated version/disk observations. Do not generalize AWS failover acceptance to Azure or Kernel-based Virtual Machine (KVM) deployments.

Section titled “Choose a procedure”- Terraform lifecycle: identity, bootstrap, staging, replacement, and upgrades.
- KVM LAN live acceptance: read-only host, XC, routing, client traffic, and convergence proof.
- AWS Transit Gateway Connect: MCN transport, twelve sessions, listener routes, and acceptance.
- Azure Route Server: marketplace deployment, three NICs, registration, and dated evidence.
- Troubleshooting and FAQ: diagnose the first failing layer before rebuilding.
