300-410 Practice Question: Given this partial configuration on router R6:…

Given this partial configuration on router R6:

router bgp 65000
 neighbor 192.168.1.1 remote-as 65001

address-family ipv4

network 172.16.0.0 mask 255.255.0.0

aggregate-address 172.16.0.0 255.255.0.0

What is missing if the administrator wants to ensure that only the aggregate route is advertised to neighbor 192.168.1.1?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

The 'summary-only' keyword is missing from the aggregate-address command.

The aggregate-address command without the summary-only keyword will advertise both the aggregate and the more specific routes. To suppress the specifics, the summary-only keyword is required.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • The 'summary-only' keyword is missing from the aggregate-address command.

    Why this is correct

    Correct. Without summary-only, more specific routes are still advertised.

  • The 'network' command should be removed.

    Why it's wrong here

    Incorrect. The network command is needed to originate the prefix, but the aggregate command handles summarization.

  • The 'synchronization' command must be enabled.

    Why it's wrong here

    Incorrect. Synchronization is not related to aggregate advertisement.

  • The 'neighbor 192.168.1.1 route-map' command is needed.

    Why it's wrong here

    Incorrect. A route-map could filter specifics, but the standard method is the summary-only keyword.
