Refer to the exhibit diagram and configuration. RTBis summarizing its networks from AS
64100 with the aggregate-address command. However, the show ip route command on
RTA reveals the RTB individual networks as well as its summary route.
Which option would ensure that only the summary route would appear in the routing table of
RTA?

A.
Delete the four network statements and leave only the aggregate-addressstatement
in the BGP configuration.

B.
Add the keyword summary-onlyto the aggregate-addresscommand.

C.
Add a static route with a prefix of 192.168.24.0 255.255.252.0pointing to the
null0interface.

D.
Create a route map permitting only the summary address.

Explanation:
When the aggregate-address command is used within BGP routing, the aggregated
address is advertised, along with the more specificroutes. The exception to this rule is
through the use of the summary-only command. The “summary-only” keyword suppresses
the more specific routes and announces only the summarized route.
