Configuring IP Router Parameters
22 Router Configuration Guide
This feature uses a qos keyword to the show>router>route-table command. When this
option is specified the output includes an additional line per route entry that displays the
forwarding class and priority of the route. If a route has no fc and priority information then
the third line is blank. The following CLI shows an example:
show router route-table [family] [ip-prefix[/prefix-length]] [longer | exact] [protocol
protocol-name] qos
An example output of this command is shown below:
A:Dut-A# show router route-table 10.1.5.0/24 qos

Enabling QPPB on an IP interface
To enable QoS classification of ingress IP packets on an interface based on the QoS
information associated with the routes that best match the packets the qos-route-lookup
command is necessary in the configuration of the IP interface. The qos-route-lookup
command has parameters to indicate whether the QoS result is based on lookup of the source
or destination IP address in every packet. There are separate qos-route-lookup commands for
the IPv4 and IPv6 packets on an interface, which allows QPPB to enabled for IPv4 only, IPv6
only, or both IPv4 and IPv6. Current QPPB based on a source IP address is not supported for
IPv6 packets nor is it supported for ingress subscriber management traffic on a group
interface.
The qos-route-lookup command is supported on the following types of IP interfaces:
• base router network interfaces (config>router>interface)
• VPRN SAP and spoke SDP interfaces (config>service>vprn>interface)
• VPRN group-interfaces (config>service>vprn>sub-if>grp-if)
• IES SAP and spoke SDP interfaces (config>service>ies>interface)
• IES group-interfaces (config>service>ies>sub-if>grp-if)
