Hi! I dig everywhere but could not found the answer of my recent wccp
implementations

in my router, I could see

sh ip wccp web-cache view

     WCCP Routers Informed of:
         IP-OF-ROUTER

     WCCP Cache Engines Visible:
         IP-OF-SQUID

     WCCP Cache Engines NOT Visible:
         -none-

In router term mon, i see:

1d17h: WCCP-PKT:S00: Received valid Here_I_Am packet from IP-OF-SQUID
w/rcv_id 00001309
1d17h: WCCP-PKT:S00: Sending I_See_You packet to IP-OF-SQUID w/ rcv_id 0000130A

and so on...

in my /var/log/squid/cache.log

2007/01/04 02:53:32| wccp2HereIam: Called
2007/01/04 02:53:32| wccp2HereIam: sending to service id 0

2007/01/04 02:53:32| Incoming WCCP2_I_SEE_YOU Received ID old=4881 new=4882.

2007/01/04 02:53:32| Change not detected (26 = 26)

But in "sh ip wccp"

Global WCCP information:
    Router information:
        Router Identifier: IP-OF-ROUTER
        Protocol Version: 2.0

    Service Identifier: web-cache
        Number of Cache Engines: 1
        Number of routers: 1
        Total Packets Redirected: 0
        Redirect access-list: REDIRECTL
        Total Packets Denied Redirect: 0
        Total Packets Unassigned: 0
        Group access-list: SQUID
        Total Messages Denied to Group: 0
        Total Authentication failures: 0

In my squid.conf:

wccp2_router IP-OF-ROUTER
wccp2_rebuild_wait on
wccp2_forwarding_method 1
wccp2_return_method 1
wccp2_assignment_method 1
wccp2_service standard 0
wccp2_weight 10000
wccp2_address IP-OF-SQUID

My question is: Why my Total Packets Redirected is 0 ?
The number of object in squid cache is also not increasing also.

What wrong? I try to use wccp version 1, but it also got zero packets
redirected.

IP-OF-SQUID and IP-OF-ROUTER is on the same subnet. IP that being
redirected is also on the same subnet.

What did happen?
