Configuring route replication
About route replication
In a BGP/MPLS L3VPN network, only VPN instances that have matching route targets can communicate with each other. The route replication feature enables a VPN instance to communicate with the public network or other VPN instances by replicating routes from 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.
Procedure
To configure route replication:
Step | Command | Remarks |

1. Enter system view. | system-view | N/A |
2. Enter VPN instance view. | ip vpn-instance vpn-instance-name | N/A |
3. Enter IPv4 VPN view. | address-family ipv4 | N/A |
4. Replicate routes from the public network or other VPN instances. | route-replicate from { public | vpn-instance vpn-instance-name } protocol bgp as-number [ route-policy route-policy-name ] route-replicate from { public | vpn-instance vpn-instance-name } protocol { direct | static | { isis | ospf | rip } process-id } [ advertise ] [ route-policy route-policy-name ] | By default, a VPN instance cannot replicate routes from the public network or other VPN instances. |
