[c-nsp] Forwarding traffic to "transparent" device

[John P. Schneider]

I see this as giving the caching device an IP off of the 7600 core switch and using policy based routing (both directions)

Let me also recommend ip sla tracking. If the caching device is the one I have experience with you will want to dynamically stop the PBR in the event the caching appliance has problems 


Best Regards,
John

and why there is a problem with simply using VLANs to insert the cache into the path?
