300-410 Practice Question: Which TWO commands would a network engineer use…
Which TWO commands would a network engineer use to verify the MPLS label forwarding table on a Cisco IOS-XE router? (Choose TWO.)
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
✓
show mpls forwarding-table
The MPLS label forwarding table is verified using 'show mpls forwarding-table' and 'show mpls label table'. The former displays outgoing labels for prefixes, while the latter shows local label bindings. Other commands either show LDP neighbors or are invalid.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
show mpls forwarding-table
Why this is correct
This command displays the MPLS forwarding table, including incoming labels, outgoing labels, and next-hop information.
- ✗
show mpls ldp neighbor
Why it's wrong here
This command shows LDP neighbor relationships, not the label forwarding table.
- ✓
show mpls label table
Why this is correct
This command displays the local label information base (LIB), showing label bindings learned via LDP.
- ✗
show ip route
Why it's wrong here
This command shows the IP routing table, not MPLS label information.
- ✗
show mpls interfaces
Why it's wrong here
This command shows which interfaces are enabled for MPLS, not the label forwarding table.

MPLS Label Distribution is the process by which routers exchange labels that tell them how to forward packets across a network without looking at the IP address each time.
Key term
LDP Protocol
LDP, or Label Distribution Protocol, is a protocol that routers use to automatically exchange labels that enable MPLS (Multiprotocol Label Switching) to create fast, efficient paths for data packets across a network.
