MPLS
Not escalable. High
overhead.
Escalable but no
granular enough
Specialised
equipment. Too many
databases.
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
