The value of vRtrIfIpv6QosRouteLookup specifies whether QoS
classification of the ingress IP packets based on the route lookup
is enabled for ipv6 on this router interface.
By default the value of vRtrIfIpv6QosRouteLookup is 'none (0)',
which means the Qos classification of incoming IP packets based on
the route lookup is disabled on this interface.
When the value of vRtrIfIpv6QosRouteLookup is 'destination (1)',
the QoS route lookup is enabled and the Qos classification of incoming
IP packets is based on the destination address matching.
