(please see the red broken arrow line in the attached file). i have enabled WCCP on the four routers, i want to ask: how to controll the WCCP load balance to make sure traffic going out from the same user and come back will always go through the same WAE at the edge site, which means the traffic going out and return will via the same pair of WAE, so the optimization will happen.</P><P></P><P></P><P></P><P></P><P>thanks</P> Thu, 06 Jan 2011 03:01:02 GMT https://community.cisco.com/t5/application-networking/wae-how-to-control-load-share-with-wccp/m-p/1626329#M47778 jason_majie 2011-01-06T03:01:02Z Re: WAE, how to control load share with WCCP https://community.cisco.com/t5/application-networking/wae-how-to-control-load-share-with-wccp/m-p/1626330#M47779 <HTML><HEAD></HEAD><BODY><P>the diagram here.</P></BODY></HTML> Thu, 06 Jan 2011 03:01:46 GMT https://community.cisco.com/t5/application-networking/wae-how-to-control-load-share-with-wccp/m-p/1626330#M47779 jason_majie 2011-01-06T03:01:46Z Re: WAE, how to control load share with WCCP https://community.cisco.com/t5/application-networking/wae-how-to-control-load-share-with-wccp/m-p/1626331#M47780 <HTML><HEAD></HEAD><BODY><P>The WCCP database is replicated across both routers therefore asymetrical routing is NOT an issue.</P></BODY></HTML> Thu, 06 Jan 2011 14:20:34 GMT https://community.cisco.com/t5/application-networking/wae-how-to-control-load-share-with-wccp/m-p/1626331#M47780 sonjam 2011-01-06T14:20:34Z Re: WAE, how to control load share with WCCP https://community.cisco.com/t5/application-networking/wae-how-to-control-load-share-with-wccp/m-p/1626332#M47781 <HTML><HEAD></HEAD><BODY><P>Jason,</P><P></P><P>The two edge routers will have the same WCCP Hash or Mask buckets which will determine which WAE to send the traffic to. </P><P></P><P>Assuming you are using software based routers at the edge and you've configured the default of Hash assignment on the edge WAEs you could use the following command on the routers to see where specific hosts will be sent based on the hash calculation.</P><P></P><P></P><P><SPAN>show </SPAN><SPAN>ip</SPAN><SPAN> </SPAN><SPAN>wccp</SPAN><SPAN> <SERVICE> hash &lt;</SERVICE></SPAN><SPAN>dst-ip</SPAN><SPAN>&gt;
