In the network shown in the figure, the administrator first completes the routing configuration as shown in the options, and then enables MPLS and LDP functions on all devices and interconnected interfaces of R1-R3, so as to realize the traffic from PC1 to PC2 forwarding based on MPLS in the network.
Which of the following routing configuration options can achieve this function?

If the technical migration actions performed on the network will affect the existing network operations, the pre-set operating procedures and risk control measures must be strictly followed when implementing the technical migration project. Such projects are generally defined as cutover projects.
Which of the following operations performed in the existing network is a non-cutover item?
- A . Change the level of IS-IS Level 1-1-2 routers to Level 1-1 in batches
- B . Modify the description information of router interfaces in batches
- C . Change the area type of some OSPF routers to Stub area in batches
- D . Change the method of importing routes into BGP in batches from network to import
As shown in the OSPF network, the area numbers are marked in the figure, where area 1 is a common area, area 2 is a Totally NSSA area, and area 3 is an NSSA area. R5 introduces the external route 10.0.5.5/32 into OSPF.
Which of the following routers have a route entry for 10.0.5.5/32 in their routing tables? (Multiple choice)
- A . R2
- B . R3
- C . R4
- D . R6
