704 | Open Shortest Path First (OSPFv2 and OSPFv3)w w w . d e l l . c o m | s u p p o r t . d e l l . c o m To ensure equal intervals between the routers, manually set the dead interval of the Dell Force10 router tomatch the Cisco configuration. Use the command “ip ospf dead-interval ” in interface mode:Figure 32-6. Command Example: ip ospf intervalsFigure 32-7. OSPF Configuration with intervals setFor more information regarding this functionality or for assistance, go to www.force10networks.com/support.Configuration RequirementsThe interfaces must be in Layer-3 mode (assigned an IP address) and enabled so that they can send andreceive traffic. The OSPF process must know about these interfaces. To make the OSPF process aware ofthese interfaces, they must be assigned to OSPF areas.OSPF must be configured GLOBALLY on the system in CONFIGURATION mode.OSPF features and functions are assigned to each router using the CONFIG-INTERFACE commands foreach interface.Configuration Task List for OSPFv2 (OSPF for IPv4)Open Shortest Path First version 2 (OSPF for IPv4) is supported on platforms c e s1. Configure a physical interface.
