Refer to the exhibit. An engineer configured route redistribution in the network, but soon received reports that R2 cannot reach the 192.168.7.0/24 and 192.168.15.0/24 subnets. Which configuration resolves the issue?

  • A
  • B
  • C
  • D
Explanation

The route map redistributes only prefixes permitted by ACL 10. A wildcard mask bit of 1 ignores the corresponding address bit. Therefore, 192.168.4.0 0.0.3.255 matches 192.168.4.0/24 through 192.168.7.0/24, and 192.168.12.0 0.0.3.255 matches 192.168.12.0/24 through 192.168.15.0/24. These entries permit both required routes for redistribution while the existing deny any excludes all other unmatched routes.
