If implementing, Multi-Process OSPF, you must create an equal number of Layer 3 enabled interfaces and OSPF Process IDs. For example, if you create 4 OSPFv2 process IDs, you must have 4 interfaces with Layer 3 enabled. Use these commands on one of the interfaces to enable OSPFv2 routing. Step Command Syntax 1 ip address ip-address mask 2 no shutdown Command Mode Usage CONFIG-INTERFACE Assign an IP address to an interface. Format: A.B.C.D/M If using a Loopback interface, refer to Loopback Interfaces on page 446. CONFIG-INTERFACE Enable the interface. Return to CONFIGURATION mode to enable the OSPF process. The OSPF Process ID is the identifying number assigned to the OSPF process, and the Router ID is the IP address associated with the OSPF process. . Command Syntax router ospf process-id [vrf {vrf name}] Command Mode CONFIGURATION Usage Enable the OSPFv2 process globally. Range: 0-65535 vrf name: Enter the VRF key word and instance name to tie the OSPF instance to the VRF. All network commands under this OSPF instance are subsequently tied to the VRF instance. Once the OSPF process and the VRF are tied together, the OSPF Process ID cannot be used again in the system. If you try to enter an OSPF Process ID, or if you try to enable more OSPF processes than available Layer 3 interfaces, prior to assigning an IP address to an interface and setting the no shutdown command, you will see the following message. Message 3 C300(conf)#router ospf 1 % Error: No router ID available. In CONFIGURATION ROUTER OSPF mode, assign the Router ID. The Router ID is not required to be the router's IP address. Dell Force10 recommends using the IP address as the Router ID for easier management and troubleshooting. Command Syntax router-id ip address Command Mode Usage CONFIG-ROUTER-O Assign the Router ID for the OSPFv2 SPF-id process. IP Address: A.B.C.D Open Shortest Path First (OSPFv2) | 699
