Question

A service provider runs an MPLS L3VPN where the VRF 'CUST-A' on a PE imports route-target 65000:100. The customer now wants this PE to import only the specific prefix 10.50.0.0/16 that carries route-target 65000:100, while all other prefixes tagged with that same RT must be excluded from the VRF. Which configuration approach accomplishes this requirement?

Accepted Answer

Attach an import map (route-map matching a prefix-list for 10.50.0.0/16) to the VRF that already imports route-target 65000:100

Answer

Change the VRF to import a different route-target and ask the remote PE to re-tag only 10.50.0.0/16

Answer

Apply an outbound distribute-list on the BGP VPNv4 session to block all prefixes except 10.50.0.0/16

Answer

Configure a static route for 10.50.0.0/16 in the VRF and remove the route-target import statement entirely
