Configuring IPv4 Route Import Between Instances

Configuring IPv4 Route Import Between Instances

Usage Scenario

In BGP/MPLS IPv4 VPN networking, IPv4 users of two VPNs with matching VPN targets can communicate with each other. However, IPv4 VPN users cannot communicate with IPv4 public network users or IPv4 VPN users without matching VPN targets. To enable these users to communicate with each other, configure IPv4 route import between different instances.

IPv4 route import between instances is classified into the following types:

  • IPv4 route import between VPN and public network instances

  • IPv4 route import between VPN instances

IPv4 routes are first imported to the routing table of the specified protocol. For example, OSPF routes of VPNA are first imported to the OSPF routing table of VPNB. If the imported routes are preferred in the OSPF routing table, they will be further imported to the IPv4 routing table of VPNB to guide traffic forwarding. In addition, these routes will be advertised to other devices on the network through OSPF.

Currently, the following types of IPv4 routes can be imported between instances:
  • Direct routes

  • Static routes

  • OSPF routes

  • IS-IS routes

  • BGP routes

Pre-configuration Tasks

Before configuring IPv4 route import between instances, perform the following task:
