hi:
i have a following scenario.
both R2 and R3 act as ISPs. and R1 as company gateway router ,R4 as normal PCs.
R2 and R3 have same loopback interfaces with ip address 5.5.5.5 /24(emulate internet) .
requirement :
1. traffic which is sourced from 10.10.10.0/24 must go through s0/0 at R1
2. traffic from 20.20.20.0/24 must go through s0/1 at R1
here is what i have done
R1(config)#do show ip route
Gateway of last resort is 0.0.0.0 to network 0.0.0.0
1.0.0.0/24 is subnetted, 1 subnets
C 1.1.1.0 is directly connected, Serial0/0
2.0.0.0/24 is subnetted, 1 subnets
C 2.2.2.0 is directly connected, Serial0/1
3.0.0.0/24 is subnetted, 1 subnets
C 3.3.3.0 is directly connected, FastEthernet1/0
20.0.0.0/24 is subnetted, 1 subnets
S 20.20.20.0 [1/0] via 3.3.3.3
10.0.0.0/24 is subnetted, 1 subnets
S 10.10.10.0 [1/0] via 3.3.3.3
S* 0.0.0.0/0 is directly connected, Serial0/0
is directly connected, Serial0/1 /* i used default route to connect to 5.5.5.5.
Access lists
R1(config)#do show access-list
Standard IP access list 1
10 permit 10.10.10.0, wildcard bits 0.0.0.255
Standard IP access list 2
10 permit 20.20.20.0, wildcard bits 0.0.0.255
Route-map
R1(config)#do show route
route-map ISP_R3, permit, sequence 20
Match clauses:
ip address (access-lists): 2
Set clauses:
interface Serial0/1
Policy routing matches: 0 packets, 0 bytes
route-map ISP_R2, permit, sequence 10
Match clauses:
ip address (access-lists): 1
Set clauses:
interface Serial0/0
Policy routing matches: 0 packets, 0 bytes
i applied two policies on both serial links.
interface Serial0/0
ip address 1.1.1.1 255.255.255.0
ip policy route-map ISP_R2
serial restart-delay 0
!
interface Serial0/1
ip address 2.2.2.2 255.255.255.0
ip policy route-map ISP_R3
serial restart-delay 0
!
interface Serial0/2
no ip address
shutdown
serial restart-delay 0
!
interface Serial0/3
no ip address
shutdown
serial restart-delay 0
!
interface FastEthernet1/0
ip address 3.3.3.1 255.255.255.0

no ip http server
no ip http secure-server
ip route 0.0.0.0 0.0.0.0 Serial0/0
ip route 0.0.0.0 0.0.0.0 Serial0/1
ip route 10.10.10.0 255.255.255.0 3.3.3.3
ip route 20.20.20.0 255.255.255.0 3.3.3.3
!
!
!
access-list 1 permit 10.10.10.0 0.0.0.255
access-list 2 permit 20.20.20.0 0.0.0.255
!
route-map ISP_R3 permit 20
match ip address 2
set interface Serial0/1
!
route-map ISP_R2 permit 10
match ip address 1
set interface Serial0/0
i have no ideas what's wrong with this setup. the route-map did not work.
below is trace route output
R4(config)#do trace 5.5.5.5 source 20.20.20.20
Type escape sequence to abort.

ping 5.5.5.5 had no problems but why did both traffic go through 2.2.2.22 ?
i have no ideas what's wrong with this setup. the route-map just did not work.
I hope some one could help me out here.
thank you in advance.
