There are two 6500 core switches and firewall modules in our network environemnt.we use the same ISP as internal (between branches each other)and internet connection.The all traffics of internet will be gone through the same firewall module in our data center. We also use the same L2 switch (for internal and internet) to uplick our ISP.For using WCCP,we have to pickup an internafce as redirect interface.We know that the 'ip wccp web-cache redirect out' command must be implemented on the
outbound interface going to the Internet.But how to choose ounbound interface in our environment? how about the port connect to L2 switch? but it included in internal and inertnet traffic. Could you give me some advice? Thanks a lot!
