I am trying to bring up a third gateway using WCCP load balancing. I currently have two gateways using WCCP and working fine.
When I bring the third gateway online and enable WCCP things start to go wrong. It appears, and I am not completely sure about this, but it appears that the third gateway or even all of the gateways stop working over WCCP. Disabling the third gateway solves the issues and all is back to normal.
Working switch config:
ip wccp source-interface Vlan877
ip wccp 51 redirect-list wccp accelerated
ip address 10.10.10.65 255.255.255.248
description Lan - 4507
ip address 10.10.10.14 255.255.255.252
ip wccp 51 redirect in
mls qos trust dscp
Extended IP access list wccp
10 permit tcp 172.20.0.0 0.0.0.255 any eq www 443 (302 matches)
20 permit tcp 10.7.0.0 0.0.255.255 any eq www 443 (540 matches)
30 permit tcp 10.200.22.0 0.0.0.255 any eq www 443
40 permit tcp 10.192.22.0 0.0.0.255 any eq www 443
In the MWG's I have the following config set for WCCP.
WCCP Router : 10.10.10.65
Ports to be redirected: 80,443
Proxy listener IP address: (IP ADDRESS of each MWG respectively) 10.10.10.66, 67
Proxy listener port: 9090 (Yes the proxy is listening on 0.0.0.0)
Assign by mask (This is what my switch supports)
Input for load distribution: Source IP mask - 0x15 and Destination IP mask - 0x15
Forwarding method: L2 (This is what my switch supports)
L2 Redirect target: eth0
To recap, I have two MWG's running with this config, but connecting the third one via WCCP to the switch kills most if not all of the WCCP packet redirection.
