The correct answer is A. The preferred path is R1-R3-R4 B. During the two processes of R3 powering off and starting up, there will be packet loss. See the full explanation below for the reasoning.
Question
As shown in the figure, R1, R2, R3, and R4 all belong to OSPF area 0, and the cost value of the link is listed in the figure. The Loopback0 interfaces of R1, R2, R3, and R4 have been advertised into the OSPF protocol. R1, R2, R3 and R4 use Loopback0 as the connection interface to establish an IBGP peer relationship. R1, R2 and R3 are clients of R4. R4's directly connected network segment 172.20.1.4/32 has been advertised into the BGP protocol. Based on the above information, regarding the traffic direction of R1 accessing 172.20.1.4/32, which of the following descriptions are correct? (Multiple choice)
