Exhibit:



As shown in the figure, inter-AS VPN Option A is used. CE 1 and CE 2 belong to the same VPNAS 100 and AS 200 run IGP and LDP, respectively.
ASBRs communicate with each other through EBGP. the loopback interface address of CE 1 is 10.1.1.1/24 Suppose VPNs configured on the PE and ASBR are both named vpn-1 and CE 2 can ping CE1.
Which command can be ruin on ASBR 2 to find out route 10.1.1.1/24?

  1. Display ip routing-table vpn-instance vpn_1
  2. Display ip routing-table
  3. Display bgp vpnv4 all routing-table

Answer(s): A



Which of the following statements about the merits of the HoVPN networking are true?

  1. If the UPE are SPE are separated by an IP/IPMLS network, they can be connected through a generic routing encapsulation (GRE) or LSP runnel . A hierarchical MPLS VPN provides good scalability.
  2. The SPE and UP exchange routes and advertise labels through MP-BGP. Each UPE runs only one ­ BGP peer, reducing system overheads and simplifying configuration.
  3. The BGP/MPLS VPN can be deployed layers by layer.
    When the performance of a super strum provider edge (SPE) is insufficient, a user-end provider edge (UPE) can be added and the SPE moved to a lower layer.
    When the access capability of a UPE is insufficient, and SPE can be added.
  4. Packets are forwarded between a UPE and an SPE after being label. The UPE and SPE are connected through an interface (or a subinterface), helping reduce the usage of limited interface resources.
  5. Only local VPN routes need to be maintained on an SPE and remote routes on the SPE are represented by a default route or an aggregate route, reducing the load of the SP

Answer(s): A,B,D



Exhibit:



As shown in the figure, OSPF process 100 runs on both PEs and CEs, and VPN routers are transmitted between PE 1 and PE 2 through PGB CE 1 enables interface address 43.1.1.0/24 in area 0.A route to 43.1.10/24. However, does not exist in the routing table of CE 2.
What are the possible causes?

  1. The VPN route to 43.1.1.0/24 does not exist in the routing table of PE 2.
  2. The LSDB of PE 1 does not have the type 1 LSA generated by CE 1.
  3. The LSDB of PE 12 does not have the type 1 LSA generated by CE 1.
  4. The public network rout to 43.1.1.0/24 does not exist in the routing table of PE2 .

Answer(s): B,D



As shown in the figure, a CE requires access to the internet , and PE 1is connected to the gateway.
Configurations on PE 1 are as follows:



PE 1 is connected to the internet gateway through interface 175.311.2 CE and CE 2 cannot ping the interface.
Which of the following statements are true?

  1. NAT translation must be configured on interface pos2/1.0 instead of interface s0./01.0
  2. A private network route must be configured on the internet gateway.
  3. The public parameter of a static default route must be configured.
  4. A default must be configured on CE an CE 2.

Answer(s): B
