clear ip ospf process-id • View the current OSPFv2 status. EXEC mode show ip ospf process-id Example of Viewing the Current OSPFv2 Status Dell#show ip ospf 55555 Routing Process ospf 55555 with ID 10.10.10.10 Supports only single TOS (TOS0) routes SPF schedule delay 5 secs, Hold time between two SPFs 10 secs Number of area in this router is 0, normal 0 stub 0 nssa 0 Dell# Enabling Multi-Process OSPF (OSPFv2, IPv4 Only) Multi-process OSPF allows multiple OSPFv2 processes on a single router. For more information, refer to Multi-Process OSPF (OSPFv2, IPv4 Only) When configuring a single OSPF process, follow the same steps previously described. Repeat them as often as necessary for the desired number of processes. After the process is created, all other configurations apply as usual. 1 Assign an IP address to an interface. CONFIG-INTERFACE mode ip address ip-address mask Format: A.B.C.D/M. If you are using a Loopback interface, refer to Loopback Interfaces. 2 Enable the interface. CONFIG-INTERFACE mode no shutdown 3 Return to CONFIGURATION mode to enable the OSPFv2 process globally. CONFIGURATION mode router ospf process-id [vrf] The range is from 0 to 65535. After the OSPF process and the VRF are tied together, the OSPF process ID cannot be used again in the system. If you try to enable more OSPF processes than available Layer 3 interfaces, the following message displays: Dell(conf)#router ospf 1 % Error: No router ID available. Assigning an OSPFv2 Area After you enable OSPFv2, assign the interface to an OSPF area. Set up OSPF areas and enable OSPFv2 on an interface with the network command. You must have at least one AS area: Area 0. This is the backbone area. If your OSPF network contains more than one area, configure a backbone area (Area ID 0.0.0.0). Any area besides Area 0 can have any number ID assigned to it. The OSPFv2 process evaluates the network commands in the order they are configured. Assign the network address that is most explicit first to include all subnets of that address. For example, if you assign the network address 10.0.0.0 /8, you cannot assign the network address 10.1.0.0 /16 because it is already included in the first network address.
