Question on WCCPv2 - bucket assignment for WCCP2 load balancing
I would like to know if any one has tried out running Cisco's WAAS/WAFS/WAE or
Squid proxy as a cache cluster to leverage load balancing support in WCCPv2.
I am trying to understand WCCP based transparent network redirection in a lab setup using squid cache's WCCP and Cisco routers only. When I tried with 2 proxies for load balancing, I see that the router *always* allocates buckets in the reverse order of the specified assignment - its confusing as its not mentioned in Cisco WCCP2 protocol drafts.
In my case, the lead cache with the lowest IP specifies buckets 0-127 to itself and 128-255 to the other; but the router assigns buckets 0-127 to the second cache and 128-255 to lead cache.
I have attached the ethereal trace. Can someone explain what is going wrong here?
The issue was found in the following router versions:
Cisco 3600, IOS 12.3(1a);
Cisco 2600 IOS 12.3(9a);
Cisco 2800 IOS 12.4(3d)
WCCP status output - all the routers above show the same behavior.
From the trace, 192,168.8.231 specifies bucket distribution as its the

Thank you for your prompt and helpful responses. Yes - the bug in ethereal trace was further confusing. I am not sure though how adversely the reversed bucket assignment by the router would affect the load balancing of the caches. I will let you know of feedback once I am done with testing the load balancing of caches. Thanks again.
