634 | Open Shortest Path First (OSPFv2 and OSPFv3)
www.dell.com | support.dell.com
Use these commands on one of the interfaces to enable OSPFv2 routing.
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.
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.
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:
Use the
no router ospf process-id command syntax in the CONFIGURATION mode to disable OSPF.
Use the
clear ip ospf process-id command syntax in EXEC Privilege mode to reset the OSPFv2 process.
