7. OSPFBGPMPLS Not escalable. High overhead. Escalable but no granular enough Specialised equipment. Too many databases. OSPF BGP MPLS EIGRP RIP

8. MPLS Constraints/Complexity  Requires (IGP) OSPF and BGP to work  Requires VRF (Virtual Routing Forwarding) to work  Creates more than 5 routing/switching tables  Specialised knowledge to design, implement and troubleshoot Advantages/Power  Minimal migration disruption if well-planned  Does not require changes on the existing routing protocols/IP address allocation  Easy integration regardless vendors or protocols  Ideal for customization: Offers virtual/customised routing for a great deal of customers in 1 device when configured through VRF (MPLS/VPN)  Simple from the user perspective (compare to smartphones) Challenges  QoS implementation, even more complex due to mapping mismatch from the IGP  Adding features to simplify particular services  Control and monitoring of MPLS devices
