routes should also be imported into OSPF. Here only introduces OSPF multi-instance
configuration in detail.
First step: Configure OSPF procedure.
Perform the following configuration in the system view.
Table 37-16 Configure OSPF procedure
Operation Command
Configure an OSPF procedure
ospf process-id [ router-id router-id-number ]
[ vpn-instance vpn-instance-name ]
Delete an OSPF procedure
undo ospf process-id
By default, the procedure index is 1.
Caution:
An OSPF procedure can only belong to one VPN instance, while one VPN instance
may contain multiple OSPF procedures. By default, an OSPF procedure belongs to
public network.
Step 2: Configure domain ID
The domain ID is used to identify an OSPF autonomous system (AS), and the same
OSPF domain must have the same domain ID. One process can be configured with
only one domain ID; different processes can be configured with the same domain ID or
different domain IDs.
Perform the following configuration in the OSPF view.
Table 37-17 Configure domain ID
Operation Command
Configure domain ID domain-id { id-number | id-addr }
Return to the default value
undo domain-id
By default, id-number is 0 and id-addr is 0.0.0.0.
It is recommended that all OSPF instances in a VPN are configured with either the
same domain ID or the default value.
