544 CHAPTER 49: BGP/MPLS VPN CONFIGURATIONBy default, the preference value for a static route is 60. You can also specifyanother preference for the static route you are configuring.2 Configure RIP multi-instanceIf you select RIP mode for CE-PE route switching, you should then specify runningenvironment for RIP instance on PE. With this command, you can enter RIP viewand import and advertise RIP instance in the view.Perform the following configuration in the RIP view.Then configuring RIP multi-instance to import IBGP route.For details about RIP configuration, see RIP configuration section in RoutingProtocol of this manual.3 Configure OSPF multi-instance on PEIf you select OSPF mode for CE-PE route switching, you should then configureOSPF multi-instance on PE. Other configurations, such as MPLS basicconfiguration, VPN-instance configuration, do not change. Noted that when OSPFroutes and direct-connect routes are imported in the VPN instance address familyview, BGP routes should also be imported into OSPF. Here only introduces OSPFmulti-instance configuration in detail.First step: Configure OSPF process.Perform the following configuration in the system view.By default, the process index is 1.c CAUTION: An OSPF process can only belong to one VPN instance, while one VPNinstance may contain multiple OSPF processes. By default, an OSPF processbelongs to public network.Step 2: Configure Domain IDThe Domain ID is used to identify an OSPF autonomous system (AS), and the sameOSPF domain must have the same Domain ID. One process can be configured withonly one Domain ID; different processes can be configured with the same DomainID or different Domain IDs.Table 535 Configure PE-CE RIP instanceOperation CommandCreate PE-CE RIP instance ipv4-family [ unicast ] vpn-instance vpn-instance-nameDelete PE-CE RIP instance undo ipv4-family [ unicast ] vpn-instancevpn-instance-nameTable 536 Configure OSPF processOperation CommandConfigure an OSPF process ospf process-id [ router-id router-id-number ] [ vpn-instancevpn-instance-name ]Delete an OSPF process undo ospf process-id
