OSPF is deployed in a small and medium-sized network.
When checking the routing table of a certain device, it is found that there are only direct routes.
Which operation is unlikely to cause the fault?

  1. Routing protocol configuration error
  2. The routing policy is incorrectly configured
  3. Port address configuration problem
  4. The configured user authority is too low

Answer(s): D



LDP messages are exchanged between LSRs running the LDP protocol. LDP messages can be divided into four types according to their functions.
Which of the following is not an LDP message type?

  1. Discovery
  2. Announcement
  3. Conversation message
  4. Label exchange messages

Answer(s): D



Regarding the label space of MPLS, which of the description is wrong?

  1. When the penultimate hop LSR performs label switching, if the value of the label after the exchange is found to be 3, the label will be ejected by default and the packet will be sent to the last hop
  2. 1024 or more is the label space shared by dynamic signaling protocols such as LDP, RSVP-TE, MP-BGP,
    etc.
  3. 16~1023 is the label space shared by static LSP and static CR-LSP
  4. If the outgoing label value is 0, the router will directly discard the packet

Answer(s): D



When deploying MPLS/BGP IP VPN, regarding the use of BGP to exchange routing information between PE-CE, which of the following description is wrong?

  1. In the case of CE multi-homing, enabling the BGP AS number replacement function may cause routing loops, which can be used to prevent routing loops in VPN sites through BGP SoD
  2. When PE and CE use BGP to exchange routing information, if the autonomous systems of two VPN sites use the same private AS number, the AS number replacement function can be used, that is, the received AS number can be replaced with any designated AS number. The AS number in the private network route to prevent the route from being discarded due to repeated AS numbers
  3. In the Hub&Spoke scenario, when Hub-CE and Hub-PE use IGP, Spoke-PE and Spoke-CE cannot enable
    EBGP
  4. When BGP is used to exchange routing information between PE and CE, there is no need to import BGP
    -private network routes on PE
    -

Answer(s): B



Qing technology is a technology that expands the VLAN space. It achieves the function of expanding the VLAN space by adding a layer of 8D2.1Q Tag on the basis of the 8Q2.12 tag message.
Which of the following statements about qinq is wrong?

  1. Flexible QinQ can add different outer tags according to different inner tags, which is more precise in the division of user VLANs.
  2. QinQ increases the number of VLANs to 4095*4095
  3. QinQ technology can make the private network LAN transparently transmitted on the public network
  4. Basic QinQ is implemented based on the interface method

Answer(s): B



What is the Router-ID of OSPFv3?

  1. 100-bit value
  2. 128-bit value
  3. 32-bit value
  4. 64-bit value

Answer(s): C



In order to publish IPv6 routes in BGP4+, what fields are added in Update?

  1. A new NLRI type, IPv6_NLR, which carries IPv6 NLRI prefix length and IPv6 NLRI prefix
  2. A new path attribute: MP_UNREACH_NLRI
  3. A new path attribute: MP_REACH_NLRI
  4. A new path attribute: IPv6_REACH_NLRI

Answer(s): C



OSFFv2 is an IGP running on an IPv4 network: OSPFV3 is an IGP running on an IPv6 network. Compared with OSPFv2, SPFV3 has a similar LSA type, but the function is slightly different.
Which of the following is not included in the LSA type of OSPFv3?

  1. AS-External-LSA
  2. Router-LSA
  3. ASBR-Summary-LSA
  4. Network-LSA

Answer(s): C
