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
