ccielab@groupstudy.comThe second diagram I listed has a "non client" so in
that case the out keyword would include all incoming interfaces( including
this non client). Since there is a non client you would need the extra
"exclude in" command. Or you could leave off the "exclude" and just use an ACL
to filter off the E3 network. Many different options exist.David,The direction
does not actually effect where the CE sits. It just specifies when the
redirection takes place. The router will learn where the CE is via WCCP. In
the exaple you listed you could use the "in" keyword to speed up the process
since it would save the router some resources. You could also use "ip
route-cache same-interface" but its not needed. Assuming this is a basic lab
example you are referring to. There are times where you would need "out" on
the client side interface and the exit interface, but thats only if you are
doing things like ip spoofing. Hopefully you don't get something like that on
the lab :)HTH

Thanks a lot Derek but if we set it out on the second scenario wouldn't be
enough?

Mike,There was a good post a while back that explained WCCP direction. Think
of the redirect direction from the routers perspective.See the simple diagram
belowexample showing the "in" directionDestination--E0--Router--E1--Client
| E2 | Cache
Engine!interface Ethernet0/1ip address 10.10.100.6 255.255.255.0ip wccp
web-cache redirect in!another one that shows how to use the "out" direction
Non Client | E3
|Destination--E0--Router--E1--Client |
E2 | Cache Engine!interface Ethernet0/0ip
address 10.10.254.1 255.255.255.0ip wccp web-cache redirect out!interface
Ethernet0/3ip address 10.10.100.1 255.255.255.0ip wccp redirect exclude
