www.dell.com | support.dell.com Enable OSPFv2 on interfaces Each interface must have OSPFv2 enabled on it. It must be configured for Layer 3 protocol, and not be shutdown. OSPFv2 can also be assigned to a loopback interface as a virtual interface. OSPF functions and features, such as MD5 Authentication, Grace Period, Authentication Wait Time, etc, are assigned on a per interface basis. Note: If using features like MD5 Authentication, ensure all the neighboring routers are also configured for MD5. The following text presents an example of assigning an IP address to an interface and then assigning an OSPFv2 area that includes that Layer-3 interface's IP address. FTOS#(conf)#int gi 4/44 FTOS(conf-if-gi-4/44)#ip address 10.10.10.10/24 FTOS(conf-if-gi-4/44)#no shutdown FTOS(conf-if-gi-4/44)#ex FTOS(conf)#router ospf 1 FTOS(conf-router_ospf-1)#network 1.2.3.4/24 area 0 FTOS(conf-router_ospf-1)#network 10.10.10.10/24 area 1 FTOS(conf-router_ospf-1)#network 20.20.20.20/24 area 2 FTOS(conf-router_ospf-1)# FTOS# Dell Force 10 recommends that the OSPFv2 Router ID be the interface IP addresses for easier management and troubleshooting. Use the show config command in CONFIGURATION ROUTER OSPF mode to view the configuration. OSPF, by default, sends hello packets out to all physical interfaces assigned an IP address that are a subset of a network on which OSPF is enabled. Use the show ip ospf interface command to view the interfaces currently active and the areas assigned to the interfaces.
