Project Goals
Project Results

• Replace existing Frame Relay configuration with
  Multiprotocol Level Switching Virtual Private
  Network.
• Design a Virtual Private Network over MPLS, with
  the following features
• Highly scalable routing and optimal use of
  network resources for any-to-any IP connectivity.
• Integration of data and voice networks in one
  converged infrastructure
• To build on the foundation of point-to-point
  layer 2 MPLS VPNs to support client-server
  relationship.

Project Overview

• Design
• Our design consisted of five Cisco 2851 routers,
  two T1 links, two Shoretel, two D-link hubs and a
  Gigabit Switch. Our design also consisted of a
  dedicated Voice Server which provided the
  backbone of the VoIP services.
• The MPLS network was setup by encapsulating the
  Frame Relay configuration with a OSPF over RIP
  connection.
• Technical Approach
• In Frame-Mode MPLS, routers running MPLS exchange
  pure IP packets as well as labeled IP packets
  with one another in an MPLS domain.
• Labels are assigned to IP networks reachable by a
  router and then imposed on data packets forwarded
  to those IP networks.
• We used BGP, RIP V2, OSPF to define the routing
  protocols.
• Organization

• Result 1
• Designed a MPLS VPN using OSPF, RIP V2 and OSPF
  with
• Result2
• Successful implementation of Cisco Routers,
  Switch, Datalink and other network hardware.
• Result 3
• Successfully transported layer 2 packets across
  MPLS network and encapsulated Frame Mode
  transport protocol.
• Result 4
• Successful implementation of Shoretel Voice
  Server across the network for voice communication
  using IP Phones.

Project Conclusions/Outcomes

• Configured Frame Mode MPLS using a 32-bit label
  that is inserted between the Layer 2 and Layer 3
  headers. After the configuration the Layer 2
  encapsulations Frame Relay, and Ethernet are
  frame-based , which can now operate in Frame
  Mode.
• Tied together all of the router edges into a
  unified voice and private data network.
• Securely connected all of our workstations in a
  fully meshed network.
• Configured a MPLS network with minimal packet
  loss over an IP backbone while providing
  protection and decent security.
