WAAS - WCCP L2-redirection in WS-C6509-E

Question

Hi,
I have a costumer with three offices, one is the data center. The other two offices get information from the data center and between them.
Each one of these remotes offices go through two different SP to the data center, and each one is received in his own router. The core of the data center is a switch WS-C6509-E (IOS s72033-entservicesk9_wan-vz.122-18.SXF7.bin).
Because there are two different SP in the data center, the traffic redirection must be done in the switch c6500. I think that the following configuration is the correct one:
ip wccp version 2
ip wccp 61 redirect-list 101
ip wccp 62 redirect-list 101
interface Vlan1
description *** WAN routers and users ***
ip address 10.0.16.1 255.255.240.0
ip wccp 62 redirect out
ip wccp 61 redirect in
interface Vlan 200
description *** WAEs ***
ip address 10.34.114.65 255.255.255.252
ip wccp redirect exclude in
interface Vlan201
description *** Servers and Users 1 ***
ip address 10.15.240.1 255.255.240.0
ip wccp 61 redirect in
interface Vlan202
description *** Servers and Users 2 ***
ip address 10.16.128.1 255.255.240.0
ip wccp 61 redirect in
But now I read about the problems using GRE redirection in the switch c6500. I read too that the best way to do this is using L2-redirection, but I don't have any idea of how to do this. I am using the WAAS version 4.1.1.
Can anybody help me with explaining me the way to configure that?

Dan,
I think that the best option for this network is number one, use WCCP on the two 7206VXRs, and redirect the traffic to a single WAE in the same subnet of the hosts.
But now, I don't understand the implications of use the command “egress-method negotiated-return intercept-method wccp”. What else should I consider or configure (in the router or in the WAE) to make this interception works?
I think that the configuration on the routers and in the WAE should be something like this:
--- Router 1
ip wccp version 2
ip wccp 61 redirect-list 101
ip wccp 62 redirect-list 101
interface Serial3/3:1
ip address 10.34.113.213 255.255.255.252
ip wccp 61 redirect in
ip wccp 62 redirect in
interface GigabitEthernet0/1
ip address 10.0.16.2 255.255.240.0
ip wccp redirect exclude in
--- Router 2
ip wccp version 2
ip wccp 61 redirect-list 101
ip wccp 62 redirect-list 101
interface Serial3/3:1
ip address 10.134.143.217 255.255.255.252
ip wccp 61 redirect in
ip wccp 62 redirect in
interface GigabitEthernet0/1
ip address 10.0.16.3 255.255.240.0
ip wccp redirect exclude in
--- WAE
interface GigabitEthernet 1/0
ip address 10.0.16.4 255.255.255.0
exit
egress-method negotiated-return intercept-method wccp
wccp router-list 1 10.0.16.2 10.0.16.3
wccp tcp-promiscuous router-list-num 1
Thanks and Regards,
