The correct answer is B. R2 GE0/0/1 interface refuses to receive ICP packets with destination port 646 C. MPLS LDP is not enabled on R2 GE0/0/1 interface D. R1 GE0/0/1 interface refuses to receive packets with UDP destination port 646. See the full explanation below for the reasoning.
Question
In the OSPF network shown in the figure, R1 and R2 achieve intercommunication through Lopback0 interface 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 10.0.2.2
- BR2 GE0/0/1 interface refuses to receive ICP packets with destination port 646
- CMPLS LDP is not enabled on R2 GE0/0/1 interface
- DR1 GE0/0/1 interface refuses to receive packets with UDP destination port 646
