3.4.3 OSPF Multi-Instance Configuration Example

Configuration Description
Users can configure multiple protocol instances. These protocol instances can belong
to the same VPN/public network or different Virtual Private Networks (VPNs). Different
protocol instances are independent of each other. They maintain the neighbor relationship,
LSDB of their own and calculate routes. However, the multiple instances belonging to the
same VPN/pbulic network share the same VPN/public network routing table. This is mainly
to divide and isolate networks.
In the following example, CE1 isolates the information flooded by PE1 and PE2. The
network topology is shown in

Figure 3-15 OSPF Multi-Instance Configuration Example

Configuration Thought
1. PE1 and CE1 establish OSPF neighbor relationship.
2. PE2 and CE1 establish OSPF neighbor relationship.
3. PE2 should not learn the link-state information related to vpn1.
