l Configuring the link layer protocol and network layer protocol for LAN interfaces and
connecting the LAN to the multi-instance CE (each service using an interface to access the
multi-instance CE)
l Binding related VPN instances to the interfaces of the multi-instance CE and PE interfaces
through which the PE accesses the multi-instance and configuring IP addresses for those
interfaces
Data Preparation
To configure a multi-VPN-instance CE, you need the following data.
No. Data
1 Names of the VPN instances corresponding with the OSPF processes used by each
service
2 OSPF process number and Router ID used by each service
3 Routes advertised by each OSPF process
3.11.2 Configuring the OSPF Multi-Instance on the PE
Different services are configured in different instances and use different OSPF process IDs.
Context
Perform the following steps on the PE that is accessed by the multi-instance CE.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
ospf process-id [ router-id router-id ] vpn-instance vpn-instance-name
The OSPF multi-instance is configured.
Different services have different OSPF process IDs. However, router IDs of different services
do not necessarily differ.
Step 3 Run:
area
area-id
The OSPF area view is displayed.
Step 4 Run:
network ip-address wildcard-mask
The IP address of the interface connected to the multi-instance CE is advertised.
