Hello ,

I have wccp deployed  in our metwork ,

Iam using the following works  great..

ip wccp 9
ip wccp 10

interface S0  -- to ISP
 ip address x.x.x.x x.x.x.x
 no ip directed-broadcast
 ip wccp 9 redirect out
 speed 100

interface Ethernet1 -- To Local LAN
 ip address x.x.x.x x.x.x.x
 no ip directed-broadcast
 ip wccp 10 redirect out
interface Ethernet2 - cache engines
 ip address ip address x.x.x.x x.x.x.x
 no ip directed-broadcast
 ip wccp redirect exclude in

Iam using this kinda  config because i wanted to send client IP address to
the webservers instead  of cache ip address.

We will have to define services in the cache engine...istead  of using
normal web-cache service , and  this configs changes from vendor to vendor.

There are lots of other  ways of deploying  wccp  , feedbacks will be of
great help to all  of us here.

Hi Group,
Derek question is very good one. I have the same doubt,  I think ip wccp
redirect in|out tells the router in which direction to look for http
request. Brian/Scott/others , if you can put some thoughts on this for which
interfaces need ip wccp web-cachse redirect in and which interfaces need ip
wccp web-cache redirect out, will be great.(these are the interfaces in
so E1--Local Lan with clients
    S0-connected to ISP
PS:pls shed light if e2 interface also has clients in addition to web cache

I have just one simple question that you may be able to help me with here
regarding WCCP. As an example I have this situation. One router with 2
Ethernet and one serial. Ethernet 1 Connected to main lan and Ethernet 2
connected to WEB Cache. And seial to the internet.

My question is that on the Ethernet connected to the Web Cache Ethernet 2. I
configured IP WCCP Redirect IN|OUT. My question is relation to the IN|OUT.
somebody please explain to me what the difference is between these two
or do I have this configued wrong, and if so what way would this be

My thinking is as follows. If the Web Cache is connected to Ethernet 2, I
two options, configure ip wccp redirect out on that interface or on Ethernet
connected to the main lan configure ip wccp redirect in, which is a better
solution because it can be fast switched and the ip wccp redirect out on
ethernet 2 cant.
