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
<ip-addr> 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
the LDP configuration sample.
