The MPLS architecture is divided into the control plane and the forwarding plane. The figure shows the relationship between various protocols and table entries. Please fill in the protocols and table entries in the corresponding positions.
R1, R2, and R3 introduce the external network 192.168.1.0/24 into BGP through the import method.
Which of the following descriptions are correct by default? (Multiple choice)
- A . For 192.168.1.0/24, R5 prefers the route received from R2
- B . For 192.168.1.0/24, R6 prefers the route received from R4
- C . For 192.168.1.0/24, if R3 is configured with "default local-preference 150", R5 will prefer the route received from R3.
- D . For 192.168.1.0/24, R4 prefers the route received from R1
In the IS-IS network shown in the figure, R1 introduces the default route through the "default-route-advertise always level-1" command, and R2 introduces the default route through the "default-route-advertise always level-2" command. Which of the following routers have default routes in their routing tables?
- A . R3
- B . R4
- C . R2
- D . R1
In the BGP/MPLS IP VPN network shown in the figure, the administrator plans to use H-Spoke networking to achieve centralized control of VPN traffic at the Hub site. Please match the RT values of the following devices one by one.
A network engineer needs to write a device upgrade guide. Which of the following should be included in the guide? (Multiple choice)
- A . How to modify sysname
- B . Version rollback process
- C . Command changes between the old and new versions
- D . How to obtain the version file
In the IS-IS network shown in the figure, R1 introduces the default route through the "default-route-advertise always level-1" command. Which of the following descriptions is correct? (Multiple choice)
- A . There is a default route in R1’s routing table.
- B . There is no default route in R3’s routing table
- C . Although R1 is configured with the "default-route-advertise always level-1" command, it cannot import the default route
- D . There is a default route in R2’s routing table
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
Generally, large-scale and important cutover projects require setting up an environment in the laboratory for advance verification, which is called laboratory testing. Successful laboratory testing means that the cutover plan is feasible and there is no need to meet with the customer for review.
- A . True
- B . False
An MPLS label is a 20-bit local identifier. Its label space is divided into special labels, static shared label space, and dynamic signaling protocol label space. Which of the following are dynamic signaling protocol labels? (Multiple choice)
- A . 1022
- B . 1024
- C . 1023
- D . 1025
In the OSPF network shown in the figure, R1 and R2 achieve intercommunication through Lopback0 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 . R1 GE0/0/1 interface refuses to receive packets with a destination IP address of 10.0.2.2
- B . R2 GE0/0/1 interface refuses to receive ICP packets with destination port 646
- C . MPLS LDP is not enabled on R2 GE0/0/1 interface
- D . R1 GE0/0/1 interface refuses to receive packets with UDP destination port 646
