In the BGP/MPLS IP VPN network shown in the figure, the administrator uses Hub-spoke networking to implement centralized control of VPN traffic at the Hub site. Which of the following RT value plans for each device is correct?
- A . PE1 VPN1: IRT=100:1; ERT=100:1
PE2 VPN1: IRT=100:1; ERT=100:1
PE3 VPN1: IRT=100:1; ERT=100:1 - B . PE1 VPN1: IRT=100:1; ERT=200:1
PE2 VPN1: IRT=100:1; ERT=200:1
PE3 VPN in: IRT=100:1; VPN_out: ERT=200:1 - C . PE1 VPN1: IRT=100:1; ERT=200:1
PE2 VPN1: IRT=100:1; ERT=200:1
PE3 VPN_in: IRT=200:1; VPN_out: ERT=100:1 - D . PE1 VPN1: IRT=100:1; ERT=200:1
PE2 VPN1: IRT=100:1; ERT=200:1
PE3 VPN1: IRT=200:1; ERT=100:1
In the network shown in the figure, the network engineer found that the path between PC1 and PC2 is not the optimal path, and the cost value of each link is the same. Based on this analysis, which of the following priorities may the switch have?
- A . SW1 32768; SW2 4096; SW3 0; SW4 8192
- B . SW1 32768; SW2 0; SW3 4096; SW4 8192
- C . SW1 0; SW2 32768; SW3 8192; SW4 4096
- D . SW1 32768; SW2 12288; SW3 4096; SW4 8192
An LDP session has been established between two devices. At this time, the administrator modifies the transmission address of one device, which will cause the LDP session to be interrupted, thereby causing service interruption.
- A . True
- B . False
In the OSPF network shown in the figure, the area numbers are marked in the figure, where area 1 is an NSSA area, and areas 2 and 3 are common areas. The "default-route-advertise always" command is configured in the SPF process of R5. Which of the following routers have default routes in their routing tables? (Multiple choice)
- A . R6
- B . R2
- C . R4
- D . R3
When an OSPFv3 message is encapsulated in an IPv6 message, which of the following is the value of the Next Header field in the IPv6 message header?
- A . 6
- B . 189
- C . 89
- D . 17
In the network shown in the figure, PC1 and PC2 are connected to the same switch and belong to the same VLAN. Which of the following reasons may cause PC1 and PC2 to be unable to communicate with each other? (Multiple choice)
- A . SW1 is configured with port isolation
- B . SW1 GE0/0/2 interface is shut down
- C . SW1 GE0/0/1 interface link failure
- D . The host has wrong static ARP configuration
In the OSPF network shown in the figure, R1 and R2 achieve intercommunication through Loopback0 interface through OSPF.
At the same time, R1 and R2 have enabled the MPLS LDP function, and the LDP transmission address is the IP address of the Loopback0 interface. The network engineer found that R1 and R2 could not establish an LDP session, so he first executed the command shown in the figure on R2. Based on this, which of the following reasons may cause the failure of establishing an LDP session between R1 and R2? (Multiple choice)
- A . R2 GE0/0/1 interface refuses to receive packets with a destination IP address of 224.0.0.2
- B . R1 GE0/0/1 interface refuses to receive packets with a destination IP address of 224.0.0.5
- C . R2 GE0/0/1 interface refuses to receive packets with source IP address 10.0.12.1
- D . R1 GE0/0/1 interface refuses to receive packets with TCP destination port 646
Which of the following descriptions about OSPFv3 are correct? (Multiple choice)
- A . OSPFv3 Router LSA and Network LSA do not contain IP addresses
- B . The LSA flooding range is added to the OSPFv3 LSA message
- C . In broadcast, NBMA, and P2MP networks, neighbors are no longer identified by IP addresses, but only by Router IDs.
- D . OSPFv3 supports multiple processes on a link
An enterprise network is shown in the figure. If CE2 is dual-owned by PE2 and PE3, a Type 5 LSA routing loop may occur. The loop can be prevented by setting the route-tag command on PE2 and PE3 devices. When the Route Tag of the route received by PE3 is the same as the local configuration, the route will be ignored.
- A . True
- B . False
In the OSPFv3 network shown in the figure, the OSPFv3 related parameters are the default configuration. When checking the LSDB on one of the devices, some content is omitted in the LSDB. The Router IDs of R1, R3, and R4 are 10.0.1.1, 10.0.3.3, and 10.0.4, respectively. The Origin Router part of some LSAs is hidden. Please complete this part.
