Hi there ppl,

A friend of mine forwarded this task to me, i dont have a definite
answer so any replies are appreciated:

R1's serial interface 1/0 will be used for a customer network by
having two sub-interfaces. Apply Quality of Service to the
corresponding sub-interfaces. Customers ip address and bandwidth to be
allocated as following

1. 1/0.1 = 10.1.1.1/24 bandwidth 15%
2. 1/0.2 = 10.1.2.1/24 bandwidth 25%
3. critical voice traffic bandwidth 50%

R1 is a HUB already having a sub-interface s0/0.123 (FR-Multipoint)
connected to two spoke routers.

This is a possible solution, not sure:

ip access-list extended s0/0.1
     permit ip any 10.1.1.0 0 0.0.0.255
ip access-list extended s0/0.2
     permit ip any 10.1.2.0 2.0 0.0.0.255
ip access-list extended VOICE
    permit udp any any range 16384 32767 precedence 5

class-map s0/0.1
    match ip add s0/0.1
class-map s0/0.2
    match ip add s0/0.2
class-map VOICE
     match ip add VOICE

Policy-map s0/0.1
    class s0/0.1
           band percent 15
class VOICE
           band percent 50

Policy-map s0/0.2
    class s0/0.2
           band percent 25
class VOICE
           band percent 50

map-class frame-relay s0/0.1
   service policy out s0/0.1
 map-class frame-relay s0/0.2
   service policy out s0/0.2

int s0/0
    frame-relay traffic- shaping
    max-reserved-band 90
int s0/0.1
      class s0/0.1
int s0/0.2
      class s0/0.2

Please ignore any syntax mistakes as i didnt get time to type it on
the router, but this logic does it make any sense for the above task??

Thanks
Aamir
