300-410 Practice Question: Which TWO commands can be used to verify the MPLS…
Which TWO commands can be used to verify the MPLS L3VPN label forwarding table on a PE 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 'show mpls forwarding-table' displays the LFIB with labels and next hops for all VPNv4 prefixes. The 'show ip bgp vpnv4 vrf <vrf-name> labels' shows the label assigned by the local PE for prefixes in a specific VRF. 'show mpls ldp bindings' shows LDP label bindings, not VPN labels. 'show ip route vrf <vrf-name>' shows the routing table, not labels. 'show bgp vpnv4 unicast all labels' is a valid alternative but not listed; 'show ip bgp vpnv4 vrf' with labels is correct.

show mpls forwarding-table
Why this is correct
Displays the LFIB including VPN labels for all prefixes.
- ✓
show ip bgp vpnv4 vrf CUSTOMER_A labels
Why this is correct
Shows the MPLS labels assigned by BGP for prefixes in the specified VRF.
- ✗
show mpls ldp bindings
Why it's wrong here
Shows LDP label bindings for IGP routes, not VPN labels.
- ✗
show ip route vrf CUSTOMER_A
Why it's wrong here
Shows the VRF routing table, not label information.
- ✗
show mpls ldp neighbor
Why it's wrong here
Displays LDP neighbor status, not label forwarding.

Same concept, more angles
1 more way this is tested on 300-410
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. A network engineer runs the following command on Router PE7: PE7# show bgp vpnv4 unicast vrf CUSTOMER_E labels Network Next Hop In Label/Out Label 10.10.10.0/24 10.0.0.8 18/22 10.20.20.0/24 10.0.0.9 19/23 Based on this output, which statement is correct?
medium- ✓ A.The router is correctly assigning labels for VPNv4 routes.
- B.The router is not receiving labels from its BGP peers.
- C.The VRF CUSTOMER_E has no routes.
- D.The label allocation is failing.
Why A: The show bgp vpnv4 unicast vrf labels command displays the label bindings for VPNv4 routes in a VRF. Each entry shows the incoming label (assigned locally) and outgoing label (assigned by the next hop). The output shows correct label assignments for two prefixes.
