On the OSPF network shown in the figure, an adjacency has been established between R1...

Configuration Analysis:

On R2 , the following configuration has been applied:

acl 200

rule deny source 10.1.0.0 0.0.3.0

rule permit

#

ospf 1

filter-policy 2000 import

This configuration uses ACL 200 to filter routes during import into the OSPF routing table on R2.

Rule deny source 10.1.0.0 0.0.3.0: Blocks routes in the range 10.1.0.0/24 to 10.1.3.0/24 (inclusive).

Rule permit: Allows all other routes to be imported.

Impact of ACL 200 on Route Import:

10.1.0.0/24 to 10.1.3.0/24: These subnets are explicitly denied by ACL 200 and will not appear in R2 ' s routing table.

10.1.4.0/24 and beyond: These subnets are permitted by the rule permit statement and will be imported into R2 ' s routing table.

Routing Table Entries on R2:

Option A (10.1.4.0/24): Exists in R2 ' s routing table because it is permitted.

Option B (10.1.3.0/24): Does not exist because it is denied by ACL 200.

Option C (10.1.2.0/24): Does not exist because it is denied by ACL 200.

Option D (10.1.1.0/24): Does not exist because it is denied by ACL 200.
