Note: If using features like MD5 Authentication, ensure all the neighboring routers are also configured for MD5. Figure 20-9 shows 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. Figure 20-9. Configuring an OSPF Area Example FTOS#(conf)#int tengig 4/44 FTOS(conf-if-te-4/44)#ip address 10.10.10.10/24 FTOS(conf-if-te-4/44)#no shutdown FTOS(conf-if-te-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# Assign Layer-3 interface with IP Address and no shutdown Assign interface's IP Address to an Area Dell Force10 recommends that the OSPFv2 Router ID be the interface IP addresses for easier management and troubleshooting. To view the configuration, use the show config command in CONFIGURATION ROUTER OSPF mode. 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. To view the interfaces currently active and the areas assigned to the interfaces, use the show ip ospf interface command (Figure 20-10).
