## 摘要

- **新稿 · VMware×Cisco AI-ready 私有云网络（09-08）：** VCF 9.1 **distributed Transit Gateway** 把南北向转发下沉到 ESX 主机；与 Cisco Nexus One 以 **BGP EVPN** 控制面、边界 **VXLAN** 对接；强调 AI 东西向/南北向饱和流量与 RoCEv2 缓冲——「加 GPU ≠ AI-ready」。
- **续档：** 09-07 open networking×Nexus One 互操作叙事仍有效；本日无深信服 aNET / SmartX Everoute / ZStack ZNS 新版本号战略稿。
- 规划含义：短线替换继续打 **标准 EVPN/VXLAN 互通 + 可随主机扩展的南北向**；智算 leaf 缓冲单独列，勿写成 HCI 开箱 DPU。

> VCF 9.1 introduces the distributed Transit Gateway. North-south forwarding moves onto the ESX hosts themselves… The Route Controller maintains BGP EVPN peering with the fabric on behalf of the hosts…
> The integration point between VCF and a Cisco Nexus One fabric is BGP EVPN… At the boundary, the Transit Gateway encapsulates in VXLAN…
> An AI-ready private cloud is not simply a private cloud with GPUs added to it.
