Volume 4-Layer 3 Configurations / Chapter 23-Open Shortest Path First (OSPF) OSPF Configuration Commands Use the following commands to enable OSPF and specify the networks that OSPF will be advertised on: Command router ospf network SUBNET-PREFIX/SUBNET-MASK-LENGTH area AREA-ID Explanation Enables the OSPF routing process and enters into router configuration mode. Defines the network address, using an IP prefix and mask length, and area ID for the interfaces that are running OSPF. In the following example, the user enables OSPF and uses the IP prefix and mask length method to assign the subnet prefix 172.16.0.0/16 to operate in OSPF area 3: dgs-6600:2>enable dgs-6600:15#configure terminal dgs-6600:15(config)#router ospf dgs-6600:15(config-router)#network 172.16.0.0/16 area 3 dgs-6600:15(config-router)#end Specifying an OSPF Router-ID The Router ID is a number assigned to each router running OSPF. Each router in an AS must have a unique Router ID. The user can manually assign a Router ID or use the default Router ID that is assigned by the router, which is the highest IP address that has been configured on the device. Use the following command to specify a Router ID for the OSPF process: Command router-id IP-ADDRESS Explanation Specifies the Router ID for the OSPF process. In the following example, the user configures the Router ID to be 10.10.10.60: dgs-6600:2>enable dgs-6600:15#configure terminal dgs-6600:15(config)#router ospf dgs-6600:15(config-router)#router-id 10.10.10.60 dgs-6600:15(config-router)#end Specifying an OSPF Router Priority Each broadcast or non-broadcast multi-access network that has at least two attached routers has a Designated Router. The Designated Router is responsible for advertising the network LSA. The router with the highest priority will be elected as the designated router. DGS-6600 Configuration Guide 219
