Akshay, Pooja Ahlawat

Abstract: There are two kinds of MPLS L3VPN topologies: Mull-Mesh and Hub-and Spoke. This paper gives the theoretical understanding of Hub-and-Spoke MPLS Layer 3 VPN Topology and its implementation using GNS3 simulator. This paper will also discuss its merit and demerits and comparison with Full-Mesh.

Keywords: MPLS, VPN, GNS3, Hub-and-spoke
