Type of Traffic Policies

Type of Traffic Policies
Type of traffic policy routing allows you to make routing decisions based on the type of traffic
that is crossing the policy router. Refer to Figure 10.4.
In this scenario, we need to create a policy on R1 so that all traffic entering R1 from R2 and
R3 will be routed based on the type of traffic. In this case, we need to send all SMTP traffic over
the connection to ISP 2 and all other traffic over the connection to ISP 1. This time, we will set
the next hop instead of the exit interface:
R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#access-list 100 permit tcp any any eq smtp
R1(config)#route-map TRAFFICPOLICY1 permit 10
R1(config-route-map)#match ip address 100
R1(config-route-map)#set ip next-hop 172.16.80.1
R1(config-route-map)#route-map TRAFFICPOLICY1 permit 20
R1(config-route-map)#set ip next-hop 172.16.90.1
R1(config-route-map)#exit
R1(config)#interface s1/0
R1(config-if)#ip policy route-map TRAFFICPOLICY1
R1(config-if)#exit
R1(config)#interface S1/1
