peer import reoriginate (BGP-EVPN address family view) (group)

Function

The peer import reoriginate command enables a device to add a regeneration flag to the routes received from BGP EVPN peer group.

The undo peer import reoriginate command restores the default configuration.

By default, a device does not add a regeneration flag to the routes received from BGP EVPN peers.

Format

peer peerGroupName import reoriginate

undo peer peerGroupName import reoriginate

Usage Guidelines

Usage Scenario

In the data center interconnect (DCI) solution, DCI-PE adds the regeneration flag to the received EVPN 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 EVPN 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 group has been enabled using the peer enable command.

Example
