hi all , glad to say that the problem has been solved :) it was squid issue , not cisco issue , i mean that my config in the diagram above was correct 100% . this is an issue when dealing with multilayer switches and its realtion with wccp . i found that using wccp asigment method to be l2 is better than has method and it solved the cpu high utilization and could finally operate the two squid cache servers on the same cisco router . thanks alot for interest and help regards -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/what-is-best-method-to-connect-two-squid-servers-on-the-same-router-tp4659922p4660273.html Sent from the Squid - Users mailing list archive at Nabble.com.
