About route replication

In a BGP/MPLS L3VPN network, only VPN instances that have matching route targets can communicate with each other.

This feature allows a VPN instance to communicate with the public network or other VPN instances by replicating routing information of the public network or other VPN instances.

In an intelligent traffic control network, traffic of different tenants is assigned to different VPNs. To enable the tenants to communicate with the public network, configure this feature to replicate routes from the public network to the VPN instances.
