I installed a WAAS with WCCP configured for traffic redirection.
It was working properly at first, that once i got a error (The error LED was on), so after checking the LOGS i found the following error log:
02-26-2009 17:52:35 Syslog.Error 192.168.95.2 2009 Feb 26 14: kernel: %WAAS-SYS-3-900000: 192.168.99.4:3809 - 192.168.2.111:2967 - opt_syn_rcv: Routing Loop detected - Packet has our own device. Packet dropped.
What could cause such a problem, note that there is an access-list configured for the WCCP redirection on the router:
ip wccp 61 redirect-list wccp-exclusion-in
ip wccp 62 redirect-list wccp-exclusion-out
and the traffic is passing between the HO and a BRANCH
