Policer vs Bandwitch vs Shaper

Hi all,

I was deeping in forum about this concepts and how they work and in which terms we can use them. But I'm very confused about how will they work.  I'm preparing a QoS config for ASR1006 in one TenGiga subinterface. The subinterface connect to a 1,3Gbps circuit of our transport Provider. We have two clients in that circuit. We should assure 300Mbps for one client with a /22 network and no more than 300Mbps. The other client can use the rest of the available bandwitdh but if there is no enough demand of traffic for the other client, can use the other client bandwitdh. Probably the circuit will no be congested in a long time, but traffic will increase for the both clients. So my questions are:

1. Which is the best config combining shaper, bandwitdh, policer and priority?.

 I use this schema_only with shapers....should it works?

policy-map PARENT

CLASS class-default

shaper 1300000000

service-policy CHILD

policy-map CHILD

CLASS classclient1

shaper 300000000

Class class-default

shaper 1300000000

IP ACCESS-LIST CLIENT1

permit ip any x.x.x.x 0.0.3.255

Class-map classlcient1

match-all name client1

interface Tengig0/1/0.300

service-policy output PARENT

Which is the best config? Should I have to apply shaper at the PARENT POLICY-map and combine bandwitdh and policy in the child policy-map to do the job?.

Thank you very much. Any help will be appreciated.
