Field Name

Field Description

Bandwidth model

Bandwidth constraint model supported. The maximum allocation model (MAM) for EXP-inferred LSPs (E-LSPs) is currently supported.

TE class

DiffServ traffic engineering class.

Traffic class

MPLS class type that corresponds to the DiffServ traffic engineering class:

  • ct0—Best effort

  • ct1—Assured forwarding

  • ct2—Expedited forwarding

  • ct3—Network control


MPLS preemption priority for this class type, a value from 0 through 7. Interior gateway protocols (IGPs) distribute information about the available bandwidth for each traffic engineering class.

Sample Output
