The correct answer is B. R1 GE0/0/1 interface refuses to receive ICP packets with destination port 646 D. R2 GEO/0/1 interface refuses to receive packets with a destination IP address of 224.0.0.2. See the full explanation below for the reasoning.
Question
In the OSPP network shown in the figure, R1 and R2 achieve Lopback0 interface interconnection 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)
Options
- AR1 GE0/0/1 interface refuses to receive packets with a destination IP address of 224.0.0.5
- BR1 GE0/0/1 interface refuses to receive ICP packets with destination port 646
- CR2 GE0/0/1 interface refuses to receive packets with source IP address 10.0.12.1
- DR2 GEO/0/1 interface refuses to receive packets with a destination IP address of 224.0.0.2
