Hello
Policy routing apply to incoming traffic from interface where is configured.
You are testing connectivity using ping, so is traffic generated locally for
the router, if you whish to apply policy-routing to this type of traffic you
need to remove the command from interface and add this global command:
ip local policy route-map pol
Note that standard acl match source address, you must change acl into
route-map:
access-list 101 permit ip any 10.34.0.0 0.0.255.255
Also you can use static route instead policy routing
ip route 10.10.1.2 255.255.255.255 10.10.1.1
ip route 10.10.1.3 255.255.255.255
I hope this help you
Regards
Rafa

Asunto: Confusing OSPF and Policy based Routing
Team,
I working with OSPF scenario
10.1.1.1 10.10.1.1 10.10.1.2
------------R1-------------FR--------------R2---------------
|
| 10.10.1.3 10.34.1.1 10.34.1.2
10.44.1.1
|---------------R3------------------------------------R4--------------------
---
|
| 10.10.1.5
|---------------R5----------------------
11.1.1.5
FR is Hub and Spoke with R1 as Hub FR is area 0 all routers see all
networks.
Problem is I can only use one Frame-relay map statement on R2,R3 and R5
pointing towards R1 it means all these three routers can ping R1 Frame-relay
interface (10.10.1.1) but they can not ping Each other FR interfaces because
pnly one FR map statement is allowed. Ospf runs well all router see all
networks but R5 cannot ping 10.34.1.1 because it got next hop as R3 serial
(10.10.1.3) but as it don't have layer 2 to layer three mapping for this IP
10.10.1.3 ( Due to lack for Frame-relay statement for this IP) it cannot
ping it. What I know is that I need to know Policy routing to use 10.10.1.1
as next hop for 10.34.1.1 from R5 but where should I use configure it I
configured at R5 serial interface for 10.34.1.1 network but its not working
see my config
For interface
!
interface Serial0
ip address 10.10.1.5 255.255.0.0
encapsulation frame-relay
no ip route-cache
no ip mroute-cache
ip policy route-map pol
frame-relay map ip 10.10.1.1 131 broadcast
For Access list
access-list 1 permit 10.34.0.0 0.0.255.255
For Route-map
route-map pol permit 10
match ip address 1
set ip next-hop 10.10.1.1
Still my router table shows
R5#sh ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter
area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is 10.10.1.2 to network 0.0.0.0
137.20.0.0/24 is subnetted, 1 subnets
O IA 137.20.20.0 [110/65] via 10.10.1.2, 01:39:11, Serial0
10.0.0.0/8 is variably subnetted, 5 subnets, 2 masks
C 10.10.0.0/16 is directly connected, Serial0
O IA 10.1.0.0/16 [110/74] via 10.10.1.1, 01:39:11, Serial0
O IA 10.4.0.0/16 [110/138] via 10.10.1.3, 01:39:11, Serial0
O IA 10.44.0.0/22 [110/129] via 10.10.1.3, 01:39:11, Serial0
O IA 10.34.0.0/16 [110/128] via 10.10.1.3, 01:39:11, Serial0
<--------------- (it is suppose to use 10.10.1.1 as next hop)
11.0.0.0/16 is subnetted, 1 subnets
C 11.1.0.0 is directly connected, Ethernet0
O*E1 0.0.0.0/0 [110/165] via 10.10.1.2, 01:39:11, Serial0
any idea,
Thanks
Iftikhar
