Implementation of BGP with similar and distinct AS numbers in MPLS VPN networks

Interior gateway routing protocols and outside gateway routing protocols are the two primary categories into which routing protocols are often divided. The main problems with IGP include inefficient bandwidth, slower convergence rates for bigger networks, and the need for more memory. To address the issues with IGP, we are moving to EGP, which includes e-BGP. BGP is mostly utilized to allow edge customer services like outside routing. BGP is used in MPLS VPN networks to provide VPNv4 services between client locations. Through the integration of MPLS VPN services with BGP, it provides customers with continuous end-to-end connection. Since the client networks and the service provider use the same routing protocol, applying the idea of redistribution is simple.
