Question

Is DiffServ code point (DSCP) classification of MPLS-tagged packets supported on the I-chip-based DPCs?

Answer

The DSCP classifier is supported on I-chip DPCs as shown in the following table.

 

MPLS Configuration

Supported Platforms

DSCP Classifier Configuration

Layer 3 VPNs and VPLSs using an LSI routing instance

M320, M120, and MX Series

Configured under class-of-service routing-instances on the egress PE router.

Layer 3 VPNs using a virtual tunnel (VT) routing instance

M320, M120, and MX Series

Configured on the core-facing interface under class-of-service interfaces on the egress PE router.

MPLS forwarding

M320, M120, and MX Series

(not supported on IQE and MX Series when ingress queuing is used)

Configured on the ingress core facing interface under class-of-service interfaces on the P or egress PE router.

VPLS using a VT routing instance

Not supported

 

MPLS forwarding when number of labels in the MPLS label stack is more than two

Not supported
