The value of vRtrIfQosRouteLookup specifies whether QoS
classification of the ingress IP packets based on the route lookup
is enabled for ipv4 on this router interface.
By default the value of vRtrIfQosRouteLookup is set to 'none (0)',
which means the Qos classification of incoming IP packets based on
the route lookup is disabled for ipv4 on this interface.
When the value of vRtrIfQosRouteLookup is 'destination (1)', the QoS
route lookup is enabled and the Qos classification of incoming
IP packets is based on the destination address matching.
When the value of vRtrIfQosRouteLookup is 'source (2)', the QoS
route lookup is enabled and the Qos classification of incoming
IP packets is based on the source address matching.
