Configuring an ASBR to Cancel the Default RT Filtering Function
By default, a PE rejects a VPN route sent by another PE (or ASBR), if the route is not imported
by any VRF on the PE. Therefore, you should disable the default filtering on an ASBR so that the
ASBR can receive all VPN routes from others PEs (or ASBRs), no matter whether these routes
are imported into the local VRF or not.
Enter the privilege mode and perform the following configuration procedure:
