As far I know, kernel 2.6.9 & up , you do need bringing up loopback0 at
cisco router (this is because wccp will use it as router identifier)
#at router :
interface lo0
ip address 172.0.0.1 255.255.255.252
no shut
#-at squid:
insmod ip_gre
ifconfig gre0 up
ip addr add 172.0.0.2 255.255.255.252 dev gre0
If you shut loopback0, wccp mechanism still alive at router, but no traffic
being redirected ( gre_tunnel is established between lo0<-->gre0 & via this
tunnel where web-traffic redirected)
Also put "ip wccp web-cache exclude in" in the router interface where squid
attached & make sure it is not same vlan where traffic redirected

Tino,
Our lookback interface is not configured and never has been in the past for
caches to work. You do bring up an interesting point of the IP address of
the gre interface. In the past i have simply used an IP that is not on our
network, maybe i can't do that anymore. What wccp directives do you have
configured in your squid.conf?
Thanks,
Bryan

Hi, Bryan
what is your interface loopback0 status & ip address at L3 6500 ? It should
be in the same subnet with your gre0 ip address.
I'm running 6500 earlier version than yours (supervisor engine-1a & msfc1),
ip cef enable, & wccpv2 work ok with squid-2.6S1, I'm using kernel 2.6.15.7
with ip_gre loaded from kernel module.
It also work when I put squid-2.6.S1 with 3620 router, ios 12.2(t) &
as5300, ios 12.0.7(t)
also, make sure iptables loaded first before running squid
rgds,
Tino

Does anyone have this problem on 2.6S1???
With debug on on the router I get this error:
Here_I_Am packet from 10.10.101.3 w/bad rcv_id 00000000
Any help would be appreciated.
Thanks,
Bryan

Hey,
I can't seem to get wccpv2 working in squid 2.6Stable1. My wccp
config is
as follows:
wccp2_router 10.10.101.1
wccp2_forwarding_method 1
wccp2_return_method 1
wccp2_service standard 0
My router only seems to see L2 redirection even though I have
specified
GRE/WCCP:
ROUTER#sho ip wcc we d
WCCP Cache-Engine information:
Web Cache ID: 10.10.101.3
Protocol Version: 2.0
State: NOT Usable
Redirection: L2
Packet Return: L2
Packets Redirected: 0
Connect Time: 00:00:29
Assignment: MASK
ROUTER#
After 30 seconds, the connect time for the cache restarts. I am
running a
2.6.17 kernel which supports WCCP in the GRE module and have this
loaded as
gre0.
Has anyone else gotten this to work under the new 2.6 release yet?
Anyone
have any suggestions?
Thanks,
Bryan
