Topology:

We will configure PBR on R1 in order to make the traffic sourced from PC1 (172.16.88.10/24) go through R2 and the traffic sourced from the rest of the networks which include PC2 (172.16.89.10/24) go through R3.

Configuration:

R1:


interface Ethernet0/0
 ip address 172.16.88.1 255.255.255.0
 ip policy route-map GOTO-R3
 half-duplex
!
interface Ethernet0/3
 ip address 172.16.89.1 255.255.255.0
 ip policy route-map GOTO-R2
 half-duplex
!
ip access-list extended Match-UDP
 permit udp any any
access-list 110 permit ip 172.16.89.0 0.0.0.255 any
no cdp log mismatch duplex
!
route-map GOTO-R2 permit 10
 match ip address 110
 set ip next-hop 10.10.1.2
!
route-map GOTO-R3 permit 10
 match ip address Match-UDP
 set ip next-hop 10.10.2.2

Verification:

We will perform a traceroute from PC1 and PC2:

We can see that the route route-map have matched:
