Critically analyse the main four factors that affect convergence time in BGP: failure detection time, event propagation time, recalculation time and forwarding table update time and explain why BGP PIC Edge is important as an optimization technique in an MPLS VPN environment. Describe the problems that PIC can manifest and solutions to overcome such issues. Illustrate your answer with specific examples on a selected topology
