When using GRE redirection and negotiated return, is it possible to place the WAEs on a segment that is not directly attached to the routers? I have seen some documentation state, "It allows the WCCP clients to be separate from the router via multiple hops. With WAAS, the WAEs need to be connected directly to a tertiary or sub-interface of the router." This has left me a little confused, but seems like it is possible with new code. If it is possible, is there any possibility on looping occuring? I assume there isn't since the packets are tunneled to and from the routers which would bypass the inspection. This would also allow me to take advantage of WAAS over a high-speed/low latency link to a datacenter that does not physically have WAEs deployed.
Any input is much appreciated,
