Introduction
Cisco Service Module-Services Ready Engine (Cisco SM-SRE) hosted by the Cisco ISR G2 have their own processors, storage, network interfaces, and memory that operate independently of the host router resources. This configuration helps to ensure maximum concurrent routing and application performance. Cisco SRE supports installing and uninstalling Cisco-authorized software, such as Cisco Unity Express, Cisco Application eXtension Platform (Cisco AXP), and Cisco IP Video Surveillance using Cisco IOS software commands and prevents unauthorized software and applications from running on Cisco SRE modules. After the application software is installed, the SMs have their own startup and run-time configurations that are independent of the Cisco IOS configuration on the host router. The SMs do not have an external console port.
Configuration
The configuration part is divided into two parts. Router config and WAAS module config.

Best Practice
In such scenario with an internal module following are usually advised:
"ip wccp 61 redirect in" the LAN interface.
"ip wccp 61 redirect in" on the WAN one.
"ip wccp redirect exclude in" on the internal interface between the WAAS and the router.
That way, we are sure that no loops are created because of the WCCP redirection.
Verify
The "sh wccp routers" command will display routers seen and not seen by this WAE.
WAE#sh wccp routers
