Refer to the exhibit. The network engineer who manages ASN 65001 is troubleshooting suboptimal routing to the 198.18.15.0/24 prefix. According to the network requirements:
✑ Routing to IP destinations in the 198.18.15.0/25 block must be preferred via the EDGE-1 PE.
✑ Routing to IP destinations in the 198.18.15.128/25 block must be preferred via the EDGE-2 PE.
✑ More specific prefixes of the 198.18.15.0/24 block must not be advertised beyond the boundaries of ASN 64611.
✑ Routing to 198.18.15.0/24 must be redundant in case one of the uplinks on INT-R1 fails.
Which configuration must the network engineer implement on INT-R1 to correct the suboptimal routing and fix the issue?

A. configure terminal route-policy ASN65001-SPECIFIC-OUT if destination in (198.18.15.0/25) then set community (no-export, peeras:65001) done endif if destination in (198.18.15.0/24) then prepend as-path 65001 3 done endif drop end-policy ! router bgp 65001 neighbor 100.65.0.1 address-family ipv4 unicast route-policy ASN65001-SPECIFIC-OUT out end

B. configure terminal route-policy ASN65001-SPECIFIC-OUT if destination in (198.18.15.0/25) then set community (internal, peeras:65001) done endif if destination in (198.18.15.0/24) then done endif drop end-policy ! router bgp 65001 neighbor 100.65.0.1 address-family ipv4 unicast route-policy ASN65001-SPECIFIC-OUT out end

C. configure terminal route-policy ASN65001-SPECIFIC-OUT if destination in (198.18.15.0/25) then set community (no-advertise, peeras:65001) done endif if destination in (198.18.15.128/25) then prepend as-path 65001 3 done endif drop end-policy ! router bgp 65001 neighbor 100.65.0.1 address-family ipv4 unicast route-policy ASN65001-SPECIFIC-OUT out end

D. configure terminal route-policy ASN65001-SPECIFIC-OUT if destination in (198.18.15.0/25) then set community (no-export, peeras:65001) done endif if destination in (198.18.15.128/25) then prepend as-path 65001 3 done endif drop end-policy ! router bgp 65001 neighbor 100.65.0.1 address-family ipv4 unicast route-policy ASN65001-SPECIFIC-OUT in end
