350-501 Architecture Practice Question
What is the purpose of the 'mpls ldp autoconfig' command on an interface?
⚠ Common exam trap
Cisco often tests the distinction between 'mpls ldp autoconfig' (which enables LDP on OSPF interfaces automatically) and 'mpls ip' (which enables MPLS forwarding on an interface), leading candidates to confuse the purpose of the command.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Automatically configure LDP on the interface
The 'mpls ldp autoconfig' command is used on an interface to automatically enable LDP on that interface for all IPv4 address families configured under the OSPF process. This eliminates the need to manually configure 'mpls ldp' on each interface, simplifying deployment in large-scale networks where LDP should be enabled on all OSPF-enabled interfaces.
