| 实施IEEE 802.1w和802.1s
- Chiara Regale- [Cisco技术] |
| 为加速网络融合并解决与生成树和虚拟 LAN ( VLAN )交互相关的地址可扩展性限制的问题, IEEE 开发了在 802.1w 中定义的快速生成树协议( RSTP )和在 802.1s 中定义的多生成树协议( MST )。这篇由思科的 Chiara Regale 撰写的文章介绍了 IEEE 802.1w 和 802.1s 的主要特性,讨论了与传统生成树协议的互操作性,并提供了一些协议移植准则 |

| 思科IP MPLS VPN
- Santiago Alvarez- [Cisco技术] |
| 多协议标签交换虚拟专用网 (MPLS VPN) 推出了一种对等模式,可以支持大规模 IP VPN 实施。这种模式极大地简化了 VPN 客户和服务供应商的路由和可管理性,与此同时,确保了 VPN 间的正确隔离。为实施该模式, MPLS VPN 需要现有 IP 路由协议扩展和一个 MPLS 传输网络。 |
