Now that we are at the subject of route-map, my experience show that the
x.x.x.x address in the command
set ip next-hop x.x.x.x
must be a directly connected router's interface, in other words, it can not
be more than one hop away.
Can anyone confirm, or dispute this?

Route-maps work in both directions, but many functions
in IOS can reference a route-map.
For more control, use an access-list as well. The one
you posted will set the next hop for any traffic going
across the ethernet interface except locally generated
traffic by the router. Also, the next hop has to be
adjancent to the router (not more then 1 hop away)
else policy routing will fail and normal forwarding
will take place.
For traffic generated by the router to be policy
routed using the route-map, you need to do 'ip local
policy (route-map-name)'.
Example:
route-map redirect perm 10
match ip address 101
match interface ethernet0
set ip next-hop x.x.x.x
This will set the next-hop for traffic on Ethernet0
that matches ACL 101. To control which direction, you
could use the source address of internal users in the
ACL.
For example:
access-list 101 perm ip 10.0.0.0 0.255.255.255 any
That would change the next-hop only for 10.x.x.x users
going anywhere. Everyone else would take routes in
routing table (normal forwarding).
Policy Routing is like a Super Static Route since you
can route traffic on anything a ACL can match on.
