Open Shortest Path First (OSPFv2 and OSPFv3) | 707Enable Multi-Process OSPFMulti-Process OSPF allows multiple OSPFv2 processes on a single router. The following list shows thenumber of processes supported on each platform type.• The E-Series supports up to 30 OSPFv2 processes.• The C-Series supports up to 6 OSPFv2 processes.• The S-Series supports up to 4 OSPFv2 processes.Follow the same steps as above, when configuring a single OSPF process. Repeat them as often asnecessary for the desired number of processes. Once the process is created, all other configurations applyas usual,Return to CONFIGURATION mode to enable the OSPF process. The OSPF Process ID is the identifyingnumber assigned to the OSPF process, and the Router ID is the IP address associated with the OSPFprocess. .Once the OSPF process and the VRF are tied together, the OSPF Process ID cannot be used again in thesystem.If you try to enable more OSPF processes than available Layer 3 interfaces you will see the followingmessage.Step Command Syntax Command Mode Usage1 ip address ip-address mask CONFIG-INTERFACE Assign an IP address to an interface.Format: A.B.C.D/MIf using a Loopback interface, refer to Loopback Interfaces onpage 427.2 no shutdown CONFIG-INTERFACE Enable the interface.Command Syntax Command Mode Usagerouter ospf process-id [vrf {vrf name}] CONFIGURATION Enable the OSPFv2 process globally.Range: 0-65535vrf name: Enter the VRF key word andinstance name to tie the OSPF instance to theVRF.
