Refer to the exhibit. Which two statements are correct regarding the routes to be
redistributed into OSPF? (Choose two.)
Router ospf 10
redistribute rip route-map rip-in
!
route-map rip-in permit 10
match ip address 10 20
set metric 100
set metric-type type-1
!
route-map rip-in deny 20
match ip address 30
!
route-map rip-in permit 30
set metric 200
set metric-type type-2
!
access-list 10 permit 10.0.10.0 0.0.0.255
access-list 20 permit 192.168.1.0 0.0.0.255
access-list 30 permit 10.0.0.0 0.255.255.255
A.
The network 192.168.1.0 will be allowed and assigned a metric of 100.
B.
The network 192.168.1.0 will be allowed and assigned a metric of 200.
C.
All networks except 10.0.0.0/8 will be allowed and assigned a metric of 200.
D.
The network 172.16.0.0/16 will be allowed and assigned a metric of 200.
E.
The network 10.0.10.0/24 will be allowed and assigned a metric of 200.
Explanation:
These rules apply when using route-map with an access-list:
* If you use an ACL in a route-map permit clause, routes that are permitted by the ACL are
redistributed.
* If you use an ACL in a route-map deny clause, routes that are permitted by the ACL are
not redistributed.
* If you use an ACL in a route-map permit or deny clause, and the ACL denies a route, then
the route-map clause match is not found and the next route-map clause is evaluated.
And in each route-map:
* Multiple match criteria in the same line use a logical OR
* Each vertical match uses a logical AND
Therefore in this question, the networks in the access lists 10 and 20 (10.0.10.0/24 &
192.168.1.0/24) will be permitted while the networkin access list 30 (10.0.0.0/8) will be
denied.
Notice that there is no “match” line in the clause 30 so all networks that are not matched
with clause 10 & 20 will be matched in the clause 30 and will be set a metric of 200, type 2 -> answer D is correct.
In this question please don’t be confused between the route-map clause number (sequence
number) and the access-list number. The “match ip address” specifies which access lists
are matched. The route-map clause number only uses to specify the order in which the
clauses are executed.
