b Configure the CQ queue
[RouterB] qos cql 1 queue 1 queue-length 100
[RouterB] qos cql 1 queue 1 serving 5000
[RouterB] qos cql 1 queue 2 queue-length 100
[RouterB] qos cql 1 queue 2 serving 1000
[RouterB] qos cql 1 protocol ip acl 107 queue 1
[RouterB] qos cql 1 protocol ip acl 108 queue 2
(CQ restricts the traffic in Tunnel0 that is larger than that in
tunnel1, and CQ is effective at the exit)
c Configure Serial0 master/slave addresses
[RouterB-Serial0] ip address 192.168.0.2 255.255.255.252
[RouterB-Serial0] ip address 192.168.1.2 255.255.255.252 sub
d Apply the CQ queue 1 to Serial0
[RouterB-Serial0] qos cq cql 1
e Configure Tunnel0
[RouterB-Tunnel0] ip address 10.1.2.1 255.255.255.0
[RouterB-Tunnel0] source 192.168.0.2
[RouterB-Tunnel0] destination 192.168.0.1
f Configure Tunnel1
[RouterB-Tunnel1] ip address 10.1.7.2 255.255.255.0
[RouterB-Tunnel1] source 192.168.1.2
[RouterB-Tunnel1] destination 192.168.1.1
