An engineer has configured R1 as EIGRP stub router. After the configuration, router R3 failed to reach to R2 loopback address.
Which action advertises R2 loopback back into the R3 routing table?

1. A. Add a static route for R2 loopback address in R1 and redistribute it to advertise to R3.
2. B. Use a leak map on R1 that matches the required prefix and apply it with the distribute list command toward R3.
3. C. Use a leak map on R3 that matches the required prefix and apply it with the EIGRP stub feature.
4. D. Add a static null route for R2 loopback address in R1 and redistribute it to advertise to R3.

Correct Answer: B
The EIGRP stub feature is useful to prevent unnecessary EIGRP queries and to filter some routes that you advertise. What if you want to configure your router as a stub router but still make an exception to some routes that it advertises? That is possible with the leak-map feature. This is how to configure leak-map in this question:
R1(config)#ip access-list standard R2_L0 R1(config-std-nacl)#permit host 2.2.2.2 R1(config)#route-map R2_L0_LEAK R2(config-route-map)#match ip address R2_L0 R1(config)#router eigrp 1
R1(config-router)#eigrp stub leak-map R2_L0_LEAK
