Hi,
I have 1 WAN Router and 2 WAVE devices configured in WCCP. The configuration works fine except that only the first WAVE that sees the router and established the WCCP receives the traffic. What I mean is that both WAVEs see the router and vice versa. When I establish the WCCP connection, the first WAVE to establish it becomes LEAD WAE and the other one does not get packets. If I disconnect the lead WAE or change its WCCP config and put it back, WCCP switches over to the other WAE and the other one is now exclusevly receiving the traffic. No load balancing is acheived.
First here's my setup:
1 WAN Router Cisco ISR G2 2911 IOS 15.2(1)T
2 Cisco WAVE-274 WAAS version 4.3.3 configured identically for WCCP.
Router IP: 10.x.y.1/22
WAVE IPs: 10.x.y.9 and 10.x.y.7 /22 and default gateway is the router 10.x.y.1
Users are on the same network 10.x.y.0/22 (is this a problem? i read in some WAAS config guide that the WAE cannot be in the same network as users)
Second here's the relevant config:
Router:
ip cef
ip wccp 61
ip wccp 62
interface GigabitEthernet0/0
description *** LAN Connection ***
ip wccp 61 redirect in
ip addr 10.x.y.1 255.255.252.0
!
interface GigabitEthernet0/1
description *** WAN Connection ***
ip wccp 62 redirect in
ip addr WAN_IP...
!
WAAS:
primary-interface GigabitEthernet 1/0
interface GigabitEthernet 1/0
ip address 10.x.y.9 255.255.252.0 (and .7 for the second WAVE)
!
interface InlineGroup 1/1
shutdown
!
wccp router-list 1 10.x.y.1
wccp tcp-promiscuous router-list-num 1 l2-redirect l2-return
wccp version 2
When I do the following on the router:
show ip wccp 61 detail
or show ip wccp 62 detail
I see:
WCCP Client information:

On the WAAS, the WCCP Assignment Settings for Load Balancing is the default: Hash. (Hash on Source IP (Service 61):)
the Egress Method is IP forwarding
I have several connections from different source IP addresses and somehow they all end up hashed on the same WAE:
ConnID Source IP:Port Dest IP:Port PeerID Accel RR
360 10.x.y.3:49463 10.q.w.36:52732 xx:xx:xx:xx:xx:xx TMDL 16.1%
373 10.x.y.4:55005 10.q.w.36:52732 xx:xx:xx:xx:xx:xx TMDL 24.8%
I checked in several places and read the best practices; the router platform support... and it seems that the config is OK

Any ideas?
