Hi Gurus,
Can you pls. check if this is correct, i want to redirect http request to my L4 and caching servers.
access-list 110 deny tcp any any neq www
access-list 110 deny tcp host 202.X.X.2 any
access-list 110 permit tcp any anywww any
route-map HTTP-TRAFFIC permit 10
match ip address 110
set interface GigabitEthernet4/1
set ip next-hop 202.X.X.2
interface FastEthernet3/4
description **To Test Client**
ip address 202.x.x.13 255.255.255.248

Hello Jepoy,
configuration looks like correct, but I would suggest you to investigate also WCCP if supported on your router and on the cache engine.
It is a more specific tool for diverting HTTP traffic to web cache and allows router to detect web cache failures
Hope to help

change your conifg to be like bellow:
use one of the following lines only
if you want to consider http reply ( almost this wil be from the web server to the requesting client )
access-list 101 permit tcp any eq www any
if you want http request use:
access-list 101 permit tcp any any eq www
route-map HTTP-TRAFFIC permit 10
match ip address 101
set ip next-hop 202.X.X.2
about the interface:
yo need to apply it to the inbound interface ( the interface where the traffic sourced from )
i think you were using the exit interface and in this case will not work
good luck

Hi guys,
My first setup would be like this
clients---6500 --- redirecting http request ---- L4 switch --- cascading caching servers
Im not seeing any packet counters on my route-map. I want to check if theres a problem on my pbr or on the L4. The route-policy is applied ingress coming from my clients. Also can the route-map also applies to vlan interface?
6500#sh access-lists 110
Extended IP access list 110
deny tcp any any neq www (18 matches)
deny tcp host 202.x.x.2 any
permit tcp any any
6500#sh route-map HTTP-TRAFFIC
route-map HTTP-TRAFFIC, permit, sequence 10
Match clauses:
ip address (access-lists): 110
Set clauses:
interface GigabitEthernet4/1
ip next-hop 202.x.x.2
Policy routing matches: 0 packets, 0 bytes
If i use wccp then do i need to use the L4? or may be the L4 would be use for the wccp, any suggestions?
tia.

Hello Jepoy,
Marwan is right: the PBR has to be applied inbound on client vlans, anyway on interface(s) that receives traffic to be redirected.
clients---6500 --- redirecting http request ---- L4 switch --- cascading caching servers
has to be:
clients--PBR -6500 --- ---- L4 switch --- cascading caching servers
about WCCP : you need to verify that web engines support it and yes it is an alternative to the use of the L4-L7 switch load balancer
Hope to help
