Define access control list:

[3Com]acl number 3101

[3Com-acl-adv-3101]rule permit tcp

[3Com]acl number 3102

[3Com-acl-adv-3102]rule permit ip

Define acl 5 node to make any TCP packet matching ACL 3101 be sent to serial 
interface serial 1/0/0.

[3Com]route-policy aaa permit node 5

[3Com-route-policy]if-match acl 3101

[3Com-route-policy]apply output-interface serial 1/0/0

Define acl 10 node not to apply the policy routing to the packet matching ACL 
3102.

[3Com]route-policy aaa deny node 10

[3Com-route-policy]if-match acl 3102

Apply policy aaa on the Ethernet interface

[3Com]interface ethernet 3/0/0

[3Com-Ethernet3/0/0]ip policy route-policy aaa

Router A sends the packets of 64 to 100 bytes long through serial 2/0/0, packets 
of 101 to 1000 bytes long through serial 2/0/1 and those of other size should be 
routed normally.

Apply IP unicast policy routing lab1 on E1/2/0 of Router A. This strategy will set 
packet of 64 to 100 bytes long to 150.1.1.2 as the IP address of next hop and set 
packet of 101 to 1000 bytes long to 151.1.1.2 as the IP address of next hop. All 
packets of other size should be routed in the method based on the destination 
address
