ONFIGURATION
By default, the preference value for a static route is 60. You can also specify
another preference for the static route you are configuring.
2 Configure RIP multi-instance
If you select RIP mode for CE-PE route switching, you should then specify running
environment for RIP instance on PE. With this command, you can enter RIP view
and import and advertise RIP instance in the view.
Perform the following configuration in the RIP view.
Table 535 Configure PE-CE RIP instance
Operation
Create PE-CE RIP instance
Delete PE-CE RIP instance
Then configuring RIP multi-instance to import IBGP route.
For details about RIP configuration, see RIP configuration section in Routing
Protocol of this manual.
3 Configure OSPF multi-instance on PE
If you select OSPF mode for CE-PE route switching, you should then configure
OSPF multi-instance on PE. Other configurations, such as MPLS basic
configuration, VPN-instance configuration, do not change. Noted that when OSPF
routes and direct-connect routes are imported in the VPN instance address family
view, BGP routes should also be imported into OSPF. Here only introduces OSPF
multi-instance configuration in detail.
First step: Configure OSPF process.
Perform the following configuration in the system view.
Table 536 Configure OSPF process
Operation
Configure an OSPF process
Delete an OSPF process
By default, the process index is 1.
CAUTION: An OSPF process can only belong to one VPN instance, while one VPN
instance may contain multiple OSPF processes. By default, an OSPF process
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.
