[: 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., , ]
