Question 56

Refer to the exhibit.

R1 is directly connected to R2 and R3. R1 is in BGP AS 123, R2 is in BGP AS 2, and R3 is in BGP AS 3. Assume that there is no connectivity issue between R1, R2 and R1, R3. Which result between BGP peers R1, R2 and R1, R3 is true?
  • Question 57

    Refer to me exhibit.

    A network engineer sets up a multihoming eBGP topology where multiple Autonomous Systems connect to ASN 64501. The engineer wants to block all the routers coming from ASN 64502. but allow all the others. For that purpose, the following AS Pam prefix 1st s being used:

    What must be fixed to achieve this result?
  • Question 58

    Refer to the exhibit.

    P1 and PE3 Cisco IOS XR routers are directly connected and have this configuration applied. The BGP session is not coming up. Assume that there is no IP reachability problem and both routers can open tcp port 179 to each other. Which action fixes the issue?
  • Question 59

    A network engineer for an ISP wants to reduce the number of iBGP adjacencies.
    A merge is taking place with another ISP network, so the network engineer needs to make both ASNs look like a single network for the Internet.
    Which BGP technology is most suitable?
  • Question 60

    Refer to me exhibit. A network engineer sets up a multihoming eBGP topology where multiple Autonomous Systems connect to ASN 64501.

    The engineer wants to block all the routers coming from ASN 64502. but allow all the others. For that purpose, the following AS Pam prefix 1st s being used:
    (config)#ip as-path access-list 10 deny _64502$
    What must be fixed to achieve this result?
