Further research into configurations required confirms that the layer-2 is a far simpler VPN solution to provision, maintain and troubleshoot.A virtual private network (VPN) extends a private network across a public network, and enables users to send and receive data across shared or public networks as if.The Layer-2 VPN solution is a simple and low maintenance solution, and that is a considerable strength, but it has a weakness.Your question is really too broad, and home networking and consumer-grade devices are explicitly off-topic here, but I will try to give you some general answers.Once the labeled packet has traversed the backbone of core P routers, it arrives at the PE router serving the remote site.

Please help me to understand this topic, please answer my questions.Layer 2 VPN is a type of VPN mode that is built and delivered on OSI layer 2 networking technologies.

In this VPN model, the customer simply connects to the provider PE using the standard Ethernet interface and protocol.This was not how Telecom or the infrastructure providers saw the potential.


Network Engineering Stack Exchange works best with JavaScript enabled.The Open Systems Interconnection (OSI) model was developed by the.Both MPLS VPN models use MPLS to forward the packets over Label Switch Paths (LSP) within the providers MPLS network.As networks grew from local area networks (LAN) to geographically dispersed networks connected by telecommunication links and Internet access became global, the debate ran its course with a general consensus — that each had a role, depending on circumstance.The network stack in the server gets to the layer-4 protocol, and the port on the layer-4 header tells the server which process in the server gets the layer-4 payload.

It simply maps the incoming IP traffic onto a prebuilt and defined tunnel for transport across the MPLS network.A specific case being when dealing with IP streams where the destination address will remain constant, surely the router could do a route look-up from the routing table once, cache the results, and switch subsequent packets.
