peer import reoriginate (BGP-VPNv4 address family view) (group)

Function

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.

Format

peer group-name import reoriginate

undo peer group-name import reoriginate

Parameters

Parameter	Description	Value
group-name	Specifies the name of a BGP peer group.	The name is a string of 1 to 47 case-sensitive characters, with spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string.

Usage Guidelines

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 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 group has been enabled using the peer group-name enable command.

Example

# Configure the device to add the regeneration flag to the routes to be received from a BGP VPNv4 peer in the BGP-VPNv4 address family view.
