Refer to the exhibit. The network administrator has configured the Customer Edge router (AS 64511) to send only summarized routes toward ISP-1 (AS 100) and ISP-2 (AS 200).

router bgp 64511

network 172.16.20.0 mask 255.255.255.0

network 172.16.21.0 mask 255.255.255.0

network 172.16.22.0 mask 255.255.255.0

network 172.16.23.0 mask 255.255.255.0

aggregate-address 172.16.20.0 255.255.252.0

After this configuration. ISP-1 and ISP-2 continue to receive the specific routes and the summary route. Which configuration resolves the issue?
