Usage Guideline DXS-3600 Series 10GbE Layer 2/3 Switch CLI Reference Guide The authentication for OSPF messages can be either operated in password mode or MD5 digest mode. This command defines the message digest key used by the MD5 digest mode. In MD5 digest mode, the OSPF message sender will compute a message digest based on the message digest key for the TX message. The message digest and the key ID will be encoded in the packet. The receiver of the packet will verify the digest in the message against the digest computed based on the locally defined message digest key corresponding to the same key ID. The same key ID on the neighboring router should be defined with the same key string. All the neighboring routers on the same interface must use the same key to exchange the OSPF packet with each other. Normally, all neighboring routers on the interface use the same key Users can verify the settings by entering the show ip ospf interface command. Example This example shows how to set the System interface (VLAN 1) authentication type to MD5. DXS-3600-32S#configure terminal DXS-3600-32S(config)#interface vlan 1 DXS-3600-32S(config-if)#ip ospf authentication message-digest DXS-3600-32S(config-if)#ip ospf message-digest-key 10 md5 yourpass DXS-3600-32S(config-if)# 40-18 ip ospf priority This command is used to configure the router priority that is used to determine the designated router for the network. Use the no command to restore it to the default value. ip ospf priority priority no ip ospf priority Parameters priority Specifies the priority of the router on the interface. The value range is 0 to 255. Default Command Mode Command Default Level Usage Guideline The default priority is 1. Interface Configuration Mode. Level: 8. (EI Mode Only Command) The OSPF router will determine a designated router for the multi-access network.This command sets the priority used to determine the OSPF Designated Router (DR) for a network. If two routers attempt to become the DR, the router with the higher router priority will be elected the DR. If the routers have the same priority, the router with the higher router ID takes precedence. Only routers with nonzero router priority values are eligible to become the designated or backup designated router. Users can verify the settings by entering the show ip ospf interface command. 391
