The peer advertise route-reoriginated command configures a device to send the routes that are regenerated in the EVPN address family to a VPNv4 peer group.
The undo peer advertise route-reoriginated command restores the default configuration.
By default, a device does not send the routes that are regenerated in the EVPN address family to a VPNv4 peer group.

Usage Scenario
A DCI is a solution for communication between DCs. In the DCI solution, after the EVPN routes that are received from the DC side and carry the VXLAN encapsulation attribute are regenerated on the DCI-PE, the DCI-PE advertises VPNv4 routes that carry the MPLS encapsulation attribute to the VPNv4 peer on the DCI backbone network.
Prerequisites
EVPN route regeneration has been enabled using the peer group-name import reoriginate command.
