Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) — Question 385

An engineer configured a leak-map command to summarize EIGRP routes and advertise specifically loopback 0 with an IP of 10.1.1.1 255.255.255.252 along with the summary route. After finishing configuration, the customer complained about not receiving the summary route with the specific loopback address. Which two configurations will fix this issue? (Choose two.)

router eigrp 1
!
route-map Leak-Route deny 10
!
interface Serial 0/0
ip summary-address eigrp 1 10.0.0.0 255.0.0.0 leak-map Leak-Route

Answer options

• A. access-list 1 permit 10.1.1.0 0.0.0.3
• B. access-list 1 permit 10.1.1.1 0.0.0.252
• C. access-list 1 and match under route-map Leak-Route
• D. route-map Leak-Route permit 10 and match access-list 1
• E. route-map Leak-Route permit 20

Correct answer: A, D

Explanation

The correct answer options A and D together ensure that the EIGRP configuration properly matches and permits the specific loopback address. Option A allows traffic for the loopback address, while option D allows the route-map to permit this traffic by matching it with the access-list. The other options do not provide the necessary configuration to permit the specific loopback address for advertisement.
