Question 1

As shown in the figure, a certain park has deployed IPv6 for service testing, and there are 4 routers in the network. Run OSPFv3 to realize network interconnection.

Regarding the LSA generated by the OSPFv3 network, which of the following statements is wrong?

A.As an ABR, R2 will generate Inter-Area-Prefix-LSA describing the IPv6 address prefix of Area 1, and advertise it to R1 and R3

B.There is a Network LSA generated by R3 in the LSDB of R1, indicating that R3 may be the DR of this link

C.R1 itself will generate Router-LSA to describe device interface information, and will receive Router-LSA generated by R2 and R3 at the same time

D.R1 will receive the two Link-LSAs generated by R2, describing the two links information connected to R2 respectively

Question 4

According to this picture, what can we know? (Multiple choice)

A.R1 does not access the route of 172.17.1.5

B.R1 access 172.17.1.5 has a loop

C.R1 accesses the path of 172.17.1.5 without any problems

D.R1 has a route to 172.17.1 5

Question 5

Regarding the description of the MPLS forwarding mechanism, which of the following is correct? (Multiple choice)

A.If the Tunnel ID value is 0x0, and then enter the MPLS forwarding process

B.If the Tunnel ID value is not 0x0, and then enter the normal IP forwarding process

C.When an IP packet enters the MRLS domain, the FIB table is the first to be checked

D.The system automatically assigns an ID to the upper-layer application that uses the tunnel, also known as Tunnel ID
