In a BGP/MPLS IP VPN network, VPNv4 routing transfers carry Export RT values. Which of the following path attributes does MP-BGP use to carry Export RT?
- A . Extended Community
- B . AS Path
- C . Local Preference
- D . MP_REACH_NLRI
To support the processing and calculation of IPv6 routes, IS-IS adds a new MLPID in TLV No. 129.
MLPID is an 8-bit field that identifies a network layer protocol message. Which of the following is the MLPID value for IPv6?
- A . 204
- B . 142
- C . 232
- D . 236
When traffic accesses the backbone network, VPN isolation is required. At this time, the interface configuration of a PE router is as shown in the figure. If the administrator needs to bind the interface to VPN1 and the interface IP address remains unchanged, which of the following descriptions of the administrator’s operation is correct?
interface GigabitEthernet 0/0/1
ip address 192168.100.2 24
- A . After the administrator enters the command ip binding vpn-instance VPN1 in the interface view, it is also necessary to bind the RD value of VPN1
- B . After the administrator types the command ip binding ypn-instance VPN1 in the interface view, he needs to bind the RT value of VPN1.
- C . After the administrator enters the command ip binding vpn-instance VPN1 in the interface view, he needs to reconfigure the interface IP address
- D . The administrator can type the command ip binding vpn-instance VPN1 in the interface view.
The network logic architecture of a cutover project is shown in the figure. The purpose of the cutover is to expand a network device R4 between R2 and R3. The OSPF protocol runs between the network devices.
After the physical network is connected, when performing the cutover operation, the network engineer first mistakenly imports the backup configuration of R3 into R4. Based on this scenario, which of the following descriptions are correct? (Multiple choice)
- A . R3 and R4 can establish an OSPF neighbor relationship
- B . The OSPF neighbor relationship between R1 and R2 is not affected
- C . R1 and R3 can establish an OSPF neighbor relationship
- D . R2 and R4 can establish an OSPF neighbor relationship
I-SPF and PRC can improve the convergence speed of IS-IS routes. They both recalculate only the changed routes. The difference is that PRC does not need to calculate the node path, but updates the route based on the SPT calculated by I-SPF.
- A . True
- B . False
When a network device encounters any of the following faults, the network device will report the error message with OID 1.3.6.1.4.1.2011.5.25.155.31.3 (node name hwOspfv2IntraAreaRouteridConflict) to the network management server through SNWP?
- A . The local device deletes the OSPF routes advertised by other devices
- B . The OSPF neighbor flapping suppression status changes
- C . OSPF detects a router ID conflict within the area
- D . OSPF detects a local link DRIP address conflict
Which of the following descriptions about OSPFv3 Link-LSA and Intra-Area-Prefix-LSA are correct? (Multiple choice)
- A . Link-LSA describes the link-local address and IPv6 prefix address on this link
- B . Each device generates an Intra-Area-Prefix-LSA for each link
- C . Each device generates a Link-LSA for each link
- D . The prefix information described in the Intra-Area-Prefix-LSA is associated with the Route-LSA or Network-LSA
A message with a destination IP address of 4.4.4.4 forwarded by R1 is transmitted in an MPLS network. Part of the LSP information of R3 is shown in the figure. Which of the following devices will perform MPLS label operations during the transmission of the message? (Multiple choice)
- A . R3
- B . R4
- C . R1
- D . R2
In a Hub&Spoke network, the route transfer path of VPN1 is shown in the figure. When Hub-PE forwards the VPN1 route to Spoke PE2, which of the following AS_Path is carried?
- A . AS_Path is empty
- B . AS_Path=100
- C . AS_Path=65001, 100
- D . AS_Path=65001, 100, 65002
A large Internet service provider needs to shut down the equipment in the computer room for maintenance in batches. As a cutover project manager, which of the following time points would you prefer?
- A . Labor Day
- B . National Day
- C . Weekend
- D . Working Days
