AWS Azure OCI PVE SAM Full-Mesh Live Merge Gate

Date: 2026-06-29

Branch/build: codex/dynamic-rr-leaf-enrollment, commit 4bfdeeb1.

Result: PASS.

This records the live merge gate for a four-site SAM topology spanning AWS, Azure, OCI, and PVE. "Full-mesh" here means all AWS/Azure/OCI/PVE client-bearing leaf sites can reach each other pairwise through the SAM fabric; the tested topology uses an Azure RR/hub and does not require direct router-to-router adjacency for every site pair. Raw logs are kept outside the repository; this file records stable paths, checksum, and the key outcome. Secret material is excluded from the evidence tarball.

Topology​

  • RR: Azure routerd-fullmesh-rr, public 20.89.58.147, private 10.82.10.5.
  • AWS site:
    • aws-leaf: public 13.231.195.59, private 10.81.10.10.
    • aws-client: public 18.182.63.83, private 10.81.10.20.
  • Azure site:
    • azure-leaf: public 13.78.11.131, private 10.82.10.10.
    • azure-client: public 20.222.23.85, private 10.82.10.20.
  • OCI site:
    • oci-leaf: public 161.33.143.93, private 10.83.10.10.
    • oci-client: public 168.110.63.34, private 10.83.10.20.
  • PVE site:
    • pve-leaf: management 192.168.1.43, site gateway 10.99.9.1.
    • pve-client: management 192.168.1.47, site 10.99.9.10.

Transport tested: ipip with encryption: wireguard over public/NAT-reachable underlay. PVE is behind NAT, so WireGuard was used as the shared practical transport for this merge gate.

Assertions​

  • RR base config contained zero static SAMEnrollmentClaim resources and zero per-leaf BGPPeer resources.
  • All leaf configs were saved before deployment under the run directory configs/, with a node-by-node explanation in evidence.
  • SAMEnrollmentClient was Ready on all four leaves.
  • BGPDynamicPeer/fullmesh-leaves discovered four dynamic peers, all ESTABLISHED.
  • RR accepted four routes and rejected zero:
    • 10.81.10.20/32
    • 10.82.10.20/32
    • 10.83.10.20/32
    • 10.99.9.10/32
  • Each leaf established BGP to the RR and installed all four client /32 routes.
  • All 12 directed client-to-client checks passed with ping and SSH:
    • AWS -> Azure, Azure -> AWS
    • AWS -> OCI, OCI -> AWS
    • AWS -> PVE, PVE -> AWS
    • Azure -> OCI, OCI -> Azure
    • Azure -> PVE, PVE -> Azure
    • OCI -> PVE, PVE -> OCI

Provider Routing Evidence​

  • AWS ap-northeast-1:
    • source/destination check disabled on aws-leaf.
    • route table sends remote client /32s to the aws-leaf ENI.
  • Azure japaneast:
    • NIC IP forwarding enabled on RR and azure-leaf.
    • UDR sends remote client /32s to 10.82.10.10.
  • OCI ap-tokyo-1:
    • skip source/destination check enabled on the oci-leaf VNIC.
    • route table sends remote client /32s to the oci-leaf primary private IP target.
    • Oracle-provided Ubuntu image had a default FORWARD reject; the live test added an explicit FORWARD accept on oci-leaf.
  • PVE:
    • pve-client has explicit in-guest static routes for AWS/Azure/OCI client /32s via 10.99.9.1 dev ens19.

Cleanup Status​

Live AWS, Azure, OCI, and PVE resources were left running for immediate post-merge review. They should be destroyed after review if no further debugging is needed. A short direct-adjacency experiment was started after this run while interpreting a stricter review note; after the corrected acceptance criteria were clarified, that experiment was stopped and the hub-oriented routerd-fullmesh.service was restored on RR and leaves. The PASS evidence above is from /tmp/routerd-fullmesh-20260629T092330Z.

HTTP Control API Note​

routerd serve --http-listen exposes the mutation/control API over TCP. It is for controlled management or private underlay networks only, and must be bound only to protected addresses or shielded by equivalent network policy. In this test, Azure NSG rules restricted SSH and the enrollment API to lab and leaf source addresses; WireGuard UDP was opened for public/NAT reachability.
