题目
After the route target replacement policy is applied to the target router， the BGP session need not be refreshed manually to put the policy into operation.
Route Target Rewrite allows the administration of the routing policy to stay local to the AS.
Route target replacement is always done by the ASBR.
Route target rewrites are supported for VRF export maps.
Route target replacement can be done on incoming and outgoing BGP updates.
