The sample configurations which are listed above is the most typical one. To enable communication between

VRF, the route-target should be modified. And if the BGP AS number duplicates for the ends, the “neighbor

as-override” command should be configured to avoid the duplication of AS numbers.

Also, only BGP related configuration are listed above, to run LDP on the public network region, please refer to
