Section 7: QoS (6 Points)

• Configure R1 to give high priority to IP traffic and medium priority to DLSw going out through s0/1. Use a congestion management approach.

If you configured this correctly as shown in Example 4-40, you have scored 2 points. You need to create a priority queue to accommodate the high and medium priorities.

Example 4-40. R1 Priority Queue Configuration

 R1#show run int s0/1  priority-group 1 ! priority-list 1 protocol dlsw medium priority-list 1 protocol ip high 

• Configure R3 so that any incoming traffic on fa0/1 has medium priority.

If you configured this correctly as shown in Example 4-41, you have scored 2 points.

Example 4-41. R3 Priority Queue Configuration

 R3#show run int fa0/1 Building configuration... Current configuration : 158 bytes ! interface FastEthernet0/1 priority-group 2 ! priority-list 2 interface FastEthernet0/1 medium 

• Configure R2 s0/0Frame Relay so that real-time traffic should never reserve more than 256 kbps and no more than 50 kbps for a specific session.

If you configured this correctly as shown in Example 4-42,you have scored 2 points.

Example 4-42 shows a basic use of the RSVP configuration to reserve the bandwidth requested.

Example 4-42. R2 RSVP Configuration

 R2#sh run int s0/0 interface Serial0/0  ip address 160.10.32.2 255.255.255.0  encapsulation frame-relay  !  ip rsvp bandwidth 256 50 end
