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

I'm having exactly the same problem as Bryan on a new squid wccp system.
I have a working set too, so I'm 95% certain it's not user error.

The symptoms are exactly the same. Everything looks peachy in IOS,
except the cache IP is listed as 0.0.0.0 - state Usable. According to
the router, packets are being redirected.
Squid works fine as a normal cache, the iptables redirect works OK, the
Cisco 2600 sees the here_i_am, and replies with an I_see_you

I'm using the same syntax to create the gre tunnel, as per the faq.

The only thing that differs between the working and broken setups are
kernel and IOS versions, I'm working to remove the differences and
hopefully see where it breaks.

Another similarity to Brian's setup, is that the broken version is on a
VLAN, while the working one isn't.
