1. Can you explain to me your concern on the WCCP chat you saw on wccp0
interface? I thought they're belong there.
The WCCP control traffic should go over the IP network, not encapsulated
in GRE.
The rest looks fine (assuming IP addresses
Thanks for the response. See my comments below.

This reminds me the odd thing I ignored earlier which is I
have to define the dummy IP of the router GRE interface as the
wccp_router in the Squid for it to register with router properly.
What GRE interface on the router? Have you created

Thanks again for your helps. They're very helpful.

I did install the kernel-devel package from Redhat and tried to look for

The kernel source is in the source rpm
I thought RedHat changed their kernel source distribution package.
BTW, just to confirm, I don't need any GRE configuration on the router

That is the problem. mismatched IP addresses between the router and

There're multiple IPs in the router and it picks 204.146.97.x as its

Cisco to confirm. The Squid has 10.17.2.x IP.

They don't distribute the kernel source as a binary rpm any longer. Only

BTW, just to confirm, I don't need any
to achieve that as well.
