Queue Sharing and Redirection

An ingress queue group must be configured and applied to the ingress network FP where the

traffic is received for the VPRN. All traffic received on that FP for any binding in the VPRN

(either automatically or statically configured) which is redirected to a policer in the FP queue

group (using fp-redirect-group in the network QoS policy) will be controlled by that policer.

As a result, the traffic from all such bindings is treated as a single entity (per forwarding class)

with regard to ingress QoS control. Any fp-redirect-group multicast-policer, broadcast-

policer or unknown-policer commands in the network QoS policy are ignored for this traffic

(IP multicast traffic would use the ingress network queues or queue group related to the

network interface).

Ingress classification is based on the configuration of the ingress section of the specified

network QoS policy, noting that the dot1p and exp classification is based on the outer

Ethernet header and MPLS label whereas the DSCP applies to the outer IP header if the tunnel

encapsulation is GRE, or the DSCP in the first IP header in the payload if ler-use-dscp is

enabled in the ingress section of the referenced network QoS policy.

Ingress bandwidth control does not take into account the outer Ethernet header, the MPLS

labels/control word or GRE headers, or the FCS of the incoming frame.

The following command configures the association of the network QoS policy and the FP

queue group and instance within the network ingress of a VPRN:

When this command is configured, it overrides the QoS applied to the related network

interfaces for unicast traffic arriving on bindings in that VPRN. The IP and IPv6 criteria

statements are not supported in the applied network QoS policy
