During BGP route summarization configuration, the keyword can be used to suppress all specific routes so that only the summary route is advertised. The summary route carries the Atomic-aggregate attribute rather than the community attributes of specific routes.
Reveal Solution Discussion 0Correct Answer:
suppress-spec-map
Explanation:
Understanding BGP Route Summarization:
In Border Gateway Protocol (BGP), route summarization is a technique used to aggregate multiple specific prefixes into a broader summary prefix. This reduces the size of routing tables and improves routing efficiency.
Summarization helps to hide unnecessary details from other parts of the network while still maintaining connectivity.
HCIP-Datacom-Core Technology Training Material (BGP Route Summarization).
Suppressing Specific Routes:
When summarizing routes, the suppress-spec-map keyword is used to suppress specific prefixes so that only the summarized route is advertised.
The suppressed routes are not advertised to BGP peers; instead, only the summary route is propagated.
Reference: HCIP-Datacom Advanced Routing & Switching Technology (BGP Attributes and Summarization Techniques).
Atomic-Aggregate Attribute:
The summary route generated during BGP route summarization carries the Atomic-aggregate attribute. This attribute indicates that the summary route might not provide the exact path information available in the original specific routes.
Additionally, when using the suppress-spec-map option, the specific routes ' attributes, such as community attributes, are not included in the summary route.
Reference: HCIP-Datacom-Core Technology Training Material (BGP Path Attributes).
Conclusion:
The suppress-spec-map keyword is used to suppress specific routes when performing BGP summarization.
The summarized route includes the Atomic-aggregate attribute but does not carry community attributes from the suppressed routes.
