RFC 5462 MPLS TC Field Definition February 2009 To avoid misunderstanding about how this field may be used, it has become increasingly necessary to rename this field. This document changes the name of the field to the Traffic Class field ( TC field ). In doing so, it also updates documents that define the current use of the EXP field. mpls exp traffic class To specify the experimental (EXP) bits that will be forwarded over a member tunnel that is part of the ClassBased Tunnel Selection (CBTS) bundle, use the tunnel mpls trafficeng exp command in interface configuration mode.

MPLS and Quality of Service Cisco Press MPLS EXP 2 field: Congestion management: LLQ 3. then you need one label per class for each flow of traffic between the two endpoints of the LSP mpls exp traffic class

The MPLS header is 32 bits, where majority of it is the MPLS label. Based on RFC5462, the EXP bit has been renamed to Traffic Class field. TC name is not uses widely. (MPLS) Label Stack EXP Field Renamed to Traffic Class FieldMultiprotocol Label Switching Architecture (MPLS) Label Values MPLS Fundamentals by Luc De Ghein. Comments. The QoS EXP Matching feature allows you to classify and mark network traffic by modifying the Multiprotocol Label Switching (MPLS) experimental bits (EXP) field in IP packets. contains conceptual information and the configuration tasks for classifying and marking network traffic using the MPLS EXP field. Defining an MPLS EXP Class Map. When IP traffic enters an LSP tunnel, the ingress router marks all packets with a CoS value, which is used to place the traffic into a transmission priority queue. On the router, for SDHSONET and T3 interfaces, each interface has four transmit queues. The CoS value is encoded as part of the MPLS mpls exp traffic class Multiservice traffic: IP, MPLS MarkingColoring packets to indicate class Application marked or node configured IP Precedence or DSCP MPLS EXP You can use class of service (CoS) within MPLS networks to prioritize certain types of traffic during periods of congestion by applying packet classifiers and rewrite rules to the MPLS traffic. MPLS classifiers are global and apply to all interfaces configured as family mpls interfaces. When a Multiprotocol Label Switching (MPLS) Label Stack Entry: EXP Field Renamed to Traffic Class Field (RFC 5462, February 2009) Toggle navigation Datatracker Enable Javascript for full functionality. However, until recently, MPLS QoS markings have always made use of a field in the MPLS label header designated Experimental (Exp) as defined in RFC 3032. Recently released RFC 5462, a proposed standard, renames the Experimental field to the Traffic Class (TC) field.
