You are asked to explain why BGP PIC Edge is important as an optimization technique in Multi-protocol label switching (MPLS) VPN environment. Analyse the four factors that affect convergence time in BGP. Describe the problems that PIC can clear and solutions to end this issue. Give examples on selected geology
Topic
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.
