An engineer began to configure LDP between R1 and R2, but R1 and R2 cannot yet establish an LDP TCP connection. Which additional task must be completed to finish the implementation?
A.
Configure the mpls Idp neighbor 172.16.0.1 password command on R1
B.
Configure the mpls Idp neighbor 10.0.12.1 password command on R1
C.
Configure the no mpls Idp password option 1 command on R2
D.
Configure the no mpls Idp password option 1 command on R1
The issue here is that R1 and R2 cannot yet establish an LDP TCP connection. From the exhibit, it’s clear that the password is not required as it states “Password: not required, none, in use”. So, option C “Configure the no mpls Idp password option 1 command on R2” would be the correct answer to allow the establishment of an LDP TCP connection without requiring a password. This aligns with Cisco’s guidelines on configuring MPLS LDP where passwords might not be necessary for establishing connections between routers.
