QoS on Ingress Bindings
Traffic is tunneled between VPRN service instances on different PEs over service tunnels bound
to MPLS LSPs or GRE tunnels. The binding of the service tunnels to the underlying transport is
achieved either automatically (using the auto-bind-tunnel command) or statically (using the
spoke-sdp command; not that under the VPRN IP interface). QoS control can be applied to the
service tunnels for traffic ingressing into a VPRN service, see
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-qroup 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:
