MPLS VPN Configuration for Desklib Online Library Network

Network Decisions
We designed the above model using MPLS VPN. Here we used three PE router. These PE router
may have one or more CE. All PE router use BGP configuration to dynamically communicate with each
other. Every CE router is directly attached to PE Routers. We have chosen the layer 3 MPLS VPN model
which creates more scalable and easy to manage the VPN. HR and Payroll routers are interconnected
between them. It acts as network loop routers or backbone connection to Sydney (PE) Router. Perth has
one CE Router (Marketing). Brisbane (PE) Router has two CE Routers (R & D, Manufacture). Sydney (PE)
router has HR and Payroll
Justifications
Why we choose MPLS VPN?
 It provides the best quality performance for cloud based application in chiefly. It controls the
traffic of the massive file transfer in cloud application also
 It is carried over single carrier’s network. It secures the network more than the public network
 It provides the bandwidth depends upon the customer requirement
