An MPLS VPN is a virtual private network built on top of a service provider’s MPLS network to deliver connectivity between enterprise locations. Available in layer 2 or layer 3 options, the VPN leverages the multiprotocol and labeling capabilities of MPLS to deliver a flat, peer-to-peer network to link all of an organization’s remote sites
MPLS – A Tutorial on VPNs Layer 2 and 3. Network architects during a previous era – when there was a clear separation of function – enjoyed debating the virtues of switched or routed networks, which was stated in OSI terms as networks performing at layer-2 and layer-3 respectively. • MPLS is a layer 2+ switching • Developed to integrate IP and ATM • MPLS forwarding is done in the same way as in ATM switches • Packet forwarding is done based on Labels 4 2001 Cisco Systems, Inc. www.cisco.com MPLS Concepts • Unlike IP, classification/label can be based on: Destination Unicast address Traffic Engineering VPN QoS reach of their MPLS networks; the availability of MPLS services to all types of customers as well as true any-to-any connectivity is moving closer to reality (AT&T Knowledge Ventures, 2007, p. 2). MPLS VPN: Building on the Basics MPLS VPN is the logical next step in utilizing MPLS technology to securely transport data over IP. Mar 21, 2018 · Picture 5 depicts the captured traffic on the link between P and PE2 routers, while issuing the ping command from PC1A to PC2B. There is only one MPLS header with VPN label 21 because the P router has poped the label 18. Router PE2 removes the inner VPN header 21 and forwards ICMP request as a plain IP packet to CE2A (10.0.0.18). This is a complete guide of the MPLS protocolwhat it can do for your network and when, how and where to use it. The goal of this course is to give to the student an understanding of the real importance of MPLS and its applications. Also this course will help you understand the concepts needed for MPLS LDP MPLS labels are assigned and distributed by the Label Distribution Protocol (LDP) LDP requirements: IP connectivity – properly configured IP routing (static,OSPF,RIP) between all hosts “loopback” IP address that isn't attached to any real network interface (recommended) Homogeneous MPLS cloud – all devices inside the
To Use Level 3 BGP/MPLS VPN Two steps needed: 1. set up the VPN 2. forward packets on the VPN Identifying a BGP/MPLS VPN Three things are needed to identify a BGP/MPLS VPN 1. inner label: a way for the provider edge (PE) routers at each end of a VPN to associate a VPN with its owner’s customer edge (CE) router 2.

a normal IP packet and that concludes the MPLS trail and that is how MPLS work. I will follow this up with a simple VPN over MPLS (also called MPLS VPN) scenario to demonstrate the more technical part. A pre-requisite for this Lab session however is your understanding of BGP, EIGRP, Loopback, OSPF etc. 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.
