Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 202

Refer to the following.

Router # sh ip route eigrp -
13.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
D 13.0.0.0/8 is a summary, 00:00:32, Null0
What happens to packets that are forwarded from the 13.0.0.0/8 network to the Null0 interface?

Answer options

• A. Flagged
• B. Accepted
• C. Summarized

Correct answer:

Explanation

Packets that are sent to the Null0 interface are effectively discarded, which means they are not forwarded anywhere else. This is typically done to indicate that the route is valid but should not be used for forwarding traffic, hence the correct answer is 'Summarized' as it reflects that the route is a summary route that leads to a discard action.
