RE: [squid-users] WCCP: Web Cache ID 0.0.0.0

Henrik,

1. I can't confirm this for sure, from the router's point of view
all buckets are assigned to the only cache, but the web cache id is
0.0.0.0. Using a packet sniffer I can see that the router sends the
WCCP packets with all buckets and the cache immediately responds with no
buckets assigned.

2. For testing, I have this configuration:
        Ip wccp version 1
        Ip wccp web-cache

        On the interface we are testing (VlanX)
        Ip wccp web-cache redirect in

3. There are no ACL's applied to WCCP, or the incoming interface.
The outgoing interface (INet) only allows traffic from the network the
cache and WCCP router is on, not VLanX. Would it matter beyond that?

4. The router properly supports WCCP version 1 and 2.

I have been working with Cisco on this and they are saying, of course,
that the cache is at fault because it is sending something to the router
that it doesn't like. What's next?

Thanks,
Bryan

Look into your acls on the router, and which router interface(s) is
running WCCP.

For the router to redirect the following needs to be fulfilled:

   1. The cache and router must have agreed on the cache being used
(OK).

   2. The correct interface on the router must have WCCP enabled

   3. The acls on the router must not prevent WCCP from being used on
the
traffic in question.

   4. The router firmware must properly support WCCP (v1).

For authorative answers on 2 & 3 see the manual to your router on how to

configure your router for WCCP use. Hints can be found in the Squid FAQ.

Henrik
