IMHO:
For correct route map operation, here is the order:
1) ACL
2) Route-map
3) Apply to the routing process
If the steps are taken in different order, drastic things may occur. For
example - redistribution against a route map. If it is specified under the
routing process, but doesn't exist, what happens to the routes? Nothing
matches, so are they passed or dropped?
Comments welcome.
