Hi,
I can't seem to find any documentation about setting up squid with
WCCPv2 and multiple cisco routers. So this might be good for the
archives if someone helps me out here.
I've got WCCP running between 1 router and a Cisco router. Now I want to
add routers.
I've tried the following
Add another router entry in squid.conf
wccp2_router 192.168.0.6
wccp2_router 192.168.48.48
Create another GRE tunnel
ip tunnel add wccp0 mode gre remote 172.31.255.48 local 10.1.250.10 dev
eth0
ip addr add 10.1.250.10/32 dev wccp0
ip tunnel add wccp1 mode gre remote 172.31.255.6 local 10.1.250.10 dev
eth0
ip addr add 10.1.250.10/32 dev wccp1
ip link set wccp0 up
ip link set wccp1 up
I've configure the two routers similar
global config:
ip wccp web-cache
and one inside interface:
ip wccp web-cache redirect in
This is not doing what I needed
The cisco is seeing WCCP packets but they are not correct:

A tcpdump reveals the squid proxy is sending out UDP:2048 packets to
both routers which seems right?

Any suggestions on how the configuration should be done?
