L3 MPLS VPN – forwards based on the L3 address of the L3 PDU. The L3 PDU is encapsulated in the transport protocol (MPLS). With MPLS VPN, MP-BGP is used to distribute L3 forwarding information between sites for routes within the VPN. EVPN – Another form of multipoint L2 VPN (LAN type service). Can use MPLS or VXLAN for transport.

Layer 2 VPN emulates the behavior of a local area network (LAN) across an internet protocol (IP) or MPLS-enabled IP network allowing Ethernet devices to communicate with each other as if they were connected to a common LAN segment. DMVPN (Dynamic Multipoint VPN) is a routing technique we can use to build a VPN network with multiple sites without having to statically configure all devices. It’s a “hub and spoke” network where the spokes will be able to communicate with each other directly without having to go through the hub. Solved: Hi, I read an atricles on an internet but still bit confused for the use and defination of L2 & L3 VPN. Can someone please explain below terms and its usage : 1)L2 MPLS VPN 2)L3 MPLS VPN 10.6.2 IP Routing Via Virtual Layer 3 Switching. VPN Server has Virtual Layer 3 Switching capabilities which allow it to perform IP routing between multiple Virtual Hubs under the same VPN Server. By using this capability you can construct a large scale LAN-to-LAN VPN which works even if each individual LAN has multiple IP networks of its own.

Layer 3 VPN (L3VPN) is a type of VPN mode that is built and delivered on OSI layer 3 networking technologies. The entire communication from the core VPN infrastructure is forwarded using layer 3 virtual routing and forwarding techniques. Layer 3 VPN is also known as virtual private routed network (VPRN).

A L2 VPN acts like a layer 2 network. That is, all the devices that connect to the VPN would normally be on the same subnet, and broadcasts go to all devices. In a L3 VPN, each site makes a L3 point to point link to the MPLS provider. Each site must run a routing protocol (or use static routing) with the provider to reach other sites. Route Distinguisher. The route distinguisher has only one purpose, to make IPv4 prefixes globally unique. It is used by the PE routers to identify which VPN a packet belongs to, e.g to enable a router to distinguish between 10.0.0.1/8 for Customer A and 10.0.0.1/8 for Customer B. The VPN Client includes an extensive online HTML-based help system, including a pdf version of the.Nov 19, 2002. Using the Configuration Guide.L2VPN TUTORIAL.
