   A service provider is deploying a Layer 2 VPN between two customer sites. The PE routers are configured with the same VRF but different route distinguishers. During troubleshooting, you notice that the VPN-IPv4 routes are not being imported into the VRF on the remote PE. What is the most likely reason for this issue?

   • AThe route distinguishers must be identical for the VRF to import routes.
   • BThe route targets do not match between the two PEs.
   • CThe VRF name must be identical on both PEs.
   • DThe NLRI format is incorrect because it must carry a VPN-IPv6 prefix.
