CBWFQ Confusion

Hi Guys,

Please help answer this question:

Lets say I'm running an ISP and I've got a *customer/subscriber* *A* who
has leased a 512 K FR link from me and *customer* *B* who has leased a 256 K
FR link from me. I've configured a single multipoint FR interface on *my ISP
router in a hub and spoke fashion where the ISP router is the hub and
customers A and B are spokes*.

I want to *reserve 15% of the bandwidth* on the my multipoint interface *for
customer A*. Assuming that customer A's network address is 172.16.12.0/24,
how would I configure my ISP Hub router? I mean in my access-list, will I
match customer A's network as source or destination?

So should my configuration be:

access list 1 permit 172.16.12.0/24

class-map CUS_A
match access-group 1

policy-map CBWFQ
class CUS_A
bandwidth percent 15

int s0.1 multipoint
service policy output CBWFQ

OR

 access list 100 permit any 172.16.12.0/24

class-map CUS_A
match access-group 100

policy-map CBWFQ
class CUS_A
bandwidth percent 15

int s0.1 multipoint
service policy output CBWFQ

Thanks in advance,

Cheers!!!

Salman
