  • Question 137:

    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:

    1.

    Routing to IP destinations in the 198.18.15.0/25 block must be preferred via the EDGE-1 PE.

    2.

    Routing to IP destinations in the 198.18.15.128/25 block must be preferred via the EDGE-2 PE.

    3.

    More specific prefixes of the 198.18.15.0/24 block must not be advertised beyond the boundaries of ASN 64611.

    4.

    Routing to 198.18.15.0/24 must be redundant in case one of the uplinks on INT-R1 fails.
