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

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.
