Hi ,
There are different ways of using WCCP.
And redirect in/out will depend on the location of ur wccp servers.
The most straight forward will be
Suppose u have a small router with 2 interface
1 - ethernet for lan
2 - serial for connection to ur ISP.
Then u will have
ip wccp web-cache
int e0
ip wccp redirect in
int s0
ip wccp redirect out
Sometimes u have send Client IP address instead of ur cache engine to the
web-server due to intensive attacks or some other reasons u wanna send
the users IP.
then u have a different config :
Here
u will have use 3 subnets
different subnet in which the cache-engines will reside and two different
subnets for ur LAN and ur WAN.
u will have use
ip wccp redirect exclude in
in the subnets on which cache-engines reside.
and on both the other subnets
use : ip wccp redirect out
The configs on the cache-engines will differ for vendor to vendor.
If u use Net-apps u will have just enable Ip-spoofing on the cache-engine.
If u use Blue-Coat u have to use differ way of configuring it.
U may have to use a different service group then default wccp in the case
of sending Client IP
and when u define a different service group on the cache engine , u have
change the config on the router
use : ip wccp ( service-group no.)
instead of : ip wccp web-cache
I hope this helps a bit.
Thanks
Vishal

Subject: wccp config
is there only 1 basic configuration for wccp to work correctly?
ip wccp web-cache
!
!
int e0/0
ip wccp web-cache redirect in/out ?
i am a bit confused about the direction in which you are supposed to
apply
this:
R1-------clients----------e0/0----R2---s0/0----------------server
would you appley this to the e0/0 or to the s0/0 and which direction
would you
use <in/out>. i have heard that you can just appley it to both
interfaces
both in and out and it will take care of the rest...........is this
true?
