Refer to the exhibit. Given the above configuration commands, which two statements are true? (Choose two.)
- RTA will send the supernet route and suppress the more specific routes known to BGP.
- RTA will send the supernet route as well as all other specific BGP routes that belong to that supernet.
- RTA will create the supernet route even if no other specific routes belonging to the supernet are in the route table.
- RTA will set the atomic aggregate attribute to true.
- RTA will set the atomic aggregate attribute to false.
| Answers Explanation & Hints:
Route summarization on BGP edge routers via dynamic method is configured by specifying an aggregation network prefix. The aggregate-address command advertises the aggregated route (the supernet) in addition to the specific original component network prefixes. By using the optional summary-only keyword, the component network prefixes in the summarized network range are suppressed. When a BGP router summarizes a route, it does not advertise the AS_Path information from before the aggregation. This effect is indicated by the atomic aggregate attribute. The atomic aggregate attribute indicates that a loss of path information has occurred. |
