What is the correct BGP command to summarize the addresses from 172.16.0.0 through 172.16.15.0 into a single address that will be advertised by BGP?

  • summary-address 172.16.0.0 0.15.255.255 summary-only
  • summary-address 172.16.0.0 255.255.240.0 summary-only
  • aggregate-address 172.16.0.0 0.15.255.255 summary-only
  • aggregate-address 172.16.0.0 255.255.240.0 summary-only

Explanation: 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.
