Question 304 - 350-501 discussion

Report
Export

Refer to the exhibit.

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
