Router R1 refers to route-map fred when redistributing from EIGRP into OSPF. The entire
route-map is listed next. Which of the following answers must be true based on the
configuration as shown?
route-map fred deny 10
match ip address one
route-map fred deny 20
match ip address two
route-map fred permit 100
A.
The third route map clause will allow any routes not already filtered by the first two
clauses.
B.
Routes permitted by ACL “two” will be redistributed.
C.
Routes denied by ACL “one” will be redistributed.
D.
All routes will be filtereD.
Explanation:
The deny clauses in the route map mean that the route map will filter routes matched by that
clause. The permit or deny action of the referenced ACLs just defines whether the route is
matcheD. So, routes permitted by ACL “two” will be matched and then filtered due to the
route-map clause deny action. Routes denied by ACL “one” simply do not match the route
map clause numbered 10; such routes may or may not be redistributed depending on the
next two clauses. Clause number 100 does not have a match command, meaning it matches
all routes not otherwise matched, with a permit action, allowing these routes to be
redistributed.
