Kenneth, this is a pretty good link that should give you an understanding within the logic.

Subject: "Default action" and processing of Route-maps
Hi everyone,
When using a route-map to policy-route, if a packet is matched by a "match" statement within a particular route-map entry, then the "set" commands are carried out. I've always seen this where the actual route-map entry specifies a "permit", such as "route-map POLICY permit 10". What happens if this statement is "deny" when policy-routing? Is the "set" command never considered? Is the packet dropped, or does it merely stop processing the route-map entries and continue to be forwarded?
Of course, these values take are applied much differently when applied to redistribution. In addition to these questions, I also keep confusing what happens after all route-map entries are processed. Is the packet forwarded or discarded (in the case of policy-routing) or is the route redistributed or thrown away (in the case of redistribution).
Ultimately, what I'm really looking for is a document that can describe the flow of the processing of the route-map statements in a variety of their applications. Does anyone know of a good source, link, white paper or even book that I can use to really understand how the processing actually works?
I will lab this up, but I'd really like try to understand the theoreticals the right way first so I don't mistakenly teach myself something incorrectly because of an incomplete test procedure.
Thanks in advance,
Ken
