300-410 Practice Question: Which TWO statements about route targets (RT) in…
Which TWO statements about route targets (RT) in MPLS L3VPN are true? (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
✓
The import RT is used to filter incoming VPNv4 routes into a VRF on the receiving PE.
Route targets control the import and export of VPNv4 routes between VRFs. The export RT is attached to routes when they are advertised from a VRF to MP-BGP. The import RT determines which routes are imported into a VRF. RTs are not used for label distribution (LDP handles that) and do not affect the IGP. They are not directly involved in the VRF route distinguisher (RD) process, though RD and RT are often configured together.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The export RT is added to VPNv4 routes when they are advertised from a PE to a P router.
Why it's wrong here
Export RT is added when routes are exported from a VRF into MP-BGP, not when advertised to P routers.
- ✓
The import RT is used to filter incoming VPNv4 routes into a VRF on the receiving PE.
Why this is correct
Import RT determines which routes are installed into the VRF routing table.
- ✓
Route targets are 64-bit values typically formatted as an IP address and a 16-bit number.
Why this is correct
RTs are 64-bit (e.g., 1.1.1.1:100) and used for import/export policies.
- ✗
Route targets are used by LDP to distribute VPN labels between PEs.
Why it's wrong here
LDP distributes labels for IGP routes, not VPN labels; VPN labels are distributed via MP-BGP.
- ✗
The route target must match the route distinguisher for the VRF to function.
Why it's wrong here
RD and RT are independent; RD ensures uniqueness, RT controls route distribution.

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.
Key term
MPLS Layer 3 VPN
A technology that uses Multiprotocol Label Switching to create secure, scalable virtual private networks that connect multiple sites at the network layer, where the service provider manages routing between customer sites.
