This is one of the most common questions asked during the MPLS interviews, so this QUESTION must be prepared for before facing the interview. Here you should start answering by introducing MPLS.

Multiprotocol label switching (MPLS) offer a mechanism to process packets on the basis of labels. It is a data forwarding service that provides high-end network communications from one network node to the next on the basis of labels rather than routing table LOOKUPS. Routing table lookup for each packet makes communication sluggish but MPLS uses LFIB/forwarding table to process label from one node to another.

The MAIN benefits of using MPLS are:

• QoS integration: supports multiple levels of QoS, to manage latency, jitter and packet loss for various types of traffic (voice, video, email, bulk file TRANSFERS, etc.)
• Fast convergence: label-based switching, no need to look up routing tables
• Scalability to IP VPNs
• Low network congestion using MPLS TE
• Reliable and secure
