MPLS L2 VPN is a great topic, much harder that MPLS L3 VPN. All the time when I'm teaching MPLS VPN's I'm starting with L3 VPN's. L2 VPN's are divided in 2 main categories: VPWS (Virtual Private Wire Service) also known as point-to-point VLL (virtual leased line) VPNs and VPLS (Virtual Private Lan Service) point-to-multipoint service. Here’s what it is about: Layer 3: the service provider will participate in routing with the customer. The customer will run OSPF, EIGRP, BGP or any other routing protocol with the service provider, these routes can be shared with other sites of the customer. VPN: routing information from one customer is completely separated from other 此外,MPLS能解決VPN擴充問題和維護成本問題。 MPLS屬於第三代網絡架構,是新一代的IP高速骨幹網絡交換標準,由IETF所提出,由Cisco、ASCEND、3Com等網絡裝置大廠所  24 січ. 2021 р. 因此,对于大型电信运营商来说,目前需要解决的问题是如何部署一个易扩展、易维护的跨域MPLS L3 VPN。 跨域VPN有以下两种最普遍的形式。一种情况是对于
