Understanding WCCP on Catalyst 6509

Hello,

I want to ask about Configuration WCCP on my Catalyst 6509.

This is the topology:

This is WCCP configuration on my device 10.204.20.1:

ip access-list standard WAVE

permit 10.204.19.68

ip access-list extended WAAS-REDIRECT-LIST

permit tcp any 10.141.1.0 0.0.0.255

permit tcp 10.141.1.0 0.0.0.255 any

ip wccp 61 redirect-list WAAS-REDIRECT-LIST group-list WAVE

Interface Eth1/1

ip wccp 61 redirect in

Interface Eth1/2

ip wccp 61 redirect in

What I confused is:

1. Can I configure with only WCCP 61?

2. Can I only use it to intercept that traffic and send packet to my WAE (10.204.19.68)?

3. Can you explain what function of this command "ip wccp 61 redirect-list WAAS-REDIRECT-LIST group-list WAVE"?

When you specify the ip wccp redirect-list command, only packets that match the access list are redirected.
