Advanced Carrier Supporting Carrier Design

LDP is the most commonly used label distribution protocol in today MPLS networks. Although it lacks of Traffic Engineering, Admission Control, Fast Reroute capabilities, it scales very well because of its Multi Point to Point Label Switched Path.BGP can also assign a label for the IP and also for the VPN prefixes and in this article I will show you how BGP provides extra level of scalability for the MPLS applications.

LDP can also be used to setup a targeted LDP session which is used by many applications such as L2VPNs, Remote LFA Fast Reroute, LDP over RSVP to scale RSVP networks and so on.

In this post I will explain the differences if you use IGP + LDP and the BGP + Label for the IP prefixes.
