In the BGP routing rules, the priority of the manual summary route generated by the aggregate command is higher than the automatic summary route generated by the summary automatic command.

Question

Options

• ATRUE
• BFALSE

• A
  86% (18)
• B
  14% (3)

Explanation

Option A is correct because BGP treats administrator-configured routes as more authoritative than automatically derived ones - the aggregate command explicitly defines a summary route, giving it higher priority in route selection over the summary automatic command, which passively summarizes based on classful boundaries. This priority ordering ensures that deliberate network design decisions override automated behavior, preventing automatic summaries from inadvertently overriding intended routing policy. Option B is wrong because it inverts this relationship; automatic summaries are never preferred over manual ones in BGP's decision process. Memory tip: Think of it as "manual beats automatic" - just like a manually entered static route is more trusted than a dynamically learned one, a manually aggregated route (aggregate) outranks an automatically generated one (summary automatic).
