"permit any" is the standard behavior of acls referenced but not yet
specified

Subject: leak-map !! how does it work?

                                hello everyone while labbing i got a
question stating to advertise specific routes and summaraised one ..

i knew leak-map would do the trick and happy with it .. now my question is
leak-map has 3 rules

Three rules :

If
the leak-map is configured to reference a route-map that does not
exist, only the summary route is advertised and the more specific
routes are
suppressed

If the leak-map is configured to
reference a route-map and the route-map is referencing an access-list
that does not exist , then the summary routes and all
the specific routes are advertised

If
the leakmap is configured to reference a route-map and the route-map
matches and acl , all the permitted networks b the acl will be
advertised along with
the summary route

its completely
strange for me ... i cant see any logic ... for example if its an acl
it will do what ever we wanted to permit or deny

so when
compared iam fine with first and last points ... straight stuff ..if
acl is there it would filter if not it would ignore ..

can any one explain me how does the point no 2 works ?

Rakesh
