Question # 50

In the aggregate ipv4-address {mask | mask-length} [as-set | attribute-policy route-policy-name1 | detail-suppressed | origin-policy route-policy-name2 | suppress-policy route-policy-name3] command, multiple parameters can be used to affect the BGP summarized route and summarization result. Which of the following statements regarding this command are true?

If the origin-policy parameter is specified, only the specific routes matching route-policy are summarized.

If the attribute-policy parameter is specified, attributes of the summary route can be modified.

If the suppress-policy parameter is specified, a summary route is generated. The if-match clause of the route-policy can be used to filter specific routes to be suppressed. The specific routes matching route-policy are still advertised to other BGP peers.

If the as-set parameter is specified, the AS_Path attribute of the summary route contains AS path information about all specific routes to prevent loops.
