Which three steps are required to configure QPPB on Cisco IOS XR routers? (Choose three.)
A.
Apply a QPPB route policy to the BGP process using the table-policy command
B.
Apply a QPPB route policy to the BGP neighbor using the route-policy command
C.
Define a QPPB route policy to match the customer routes, then set the IP precedence or qosgroup
D.
Define a QPPB route policy to match the customer IP precedence or qos-group markings,then
set the BGP community
E.
Enable QPPB on an interface using the ipv4 bgp policy propagation input ip-precedence|qosgroup destination|source command
F.
Enable QPPB on an interface using the ipv4 bgp policy propagation output ip-precedence|qosgroup destination|source command
Explanation:
QoS Policy Propagation via BGP (QPPB), is a mechanism that allows propagation of quality of
service (QoS)policy and classification by the sending party based on access lists, community lists
and autonomous systempaths in the Border Gateway Protocol (BGP), thus helping to classify
based on destination instead of sourceaddress.
