Not escalable. High overhead.

Escalable but no granular enough

Specialised equipment. Too many databases.

MPLS Constraints/ComplexityRequires (IGP) OSPF and BGP to workRequires VRF (Virtual Routing Forwarding) to workCreates more than 5 routing/switching tablesSpecialised knowledge to design, implement and troubleshoot

Advantages/PowerMinimal migration disruption if well-plannedDoes not require changes on the existing routing protocols/IP address allocationEasy integration regardless vendors or protocolsIdeal 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)

ChallengesQoS implementation, even more complex due to mapping mismatch from the IGPAdding features to simplify particular servicesControl and monitoring of MPLS devices
