The peer import reoriginate command enables the function to add the regeneration flag to the routes received from the peer.
The undo peer import reoriginate command restores the default configuration.
By default, the local device does not add the regeneration flag to the routes received from the peer.
Usage Scenario
In the data center interconnect (DCI) solution, DCI-PE adds the regeneration flag to the received VPNv4 routes before sending the routes to the peer. By default, the function to add the regeneration flag to the routes received from the peer is disabled. Specifically, DCI-PE does not re-encapsulate the routes received from the peer. Therefore, to allow DCI-PE to re-encapsulate the VPNv4 routes, run the peer import reoriginate command to enable the function to add the regeneration flag to the routes received from the peer.
Prerequisites
Route exchange with a specified peer has been enabled using the peer peer-address enable command.
