The default is 1, which is the highest router priority. A value of 0 indicates that the router is not eligible to become the designated router on this network. 6. Configure the Retransmit Interval by entering the OSPF retransmit interval for the specified interface. This is the number of seconds between link-state advertisements for adjacencies belonging to this router interface. This value is also used when retransmitting database descriptions and link-state request packets. Valid values range from 1 to 3600 seconds (1 hour). The default is 5 seconds. 7. Configure the Hello Interval by entering the OSPF hello interval for the specified interface in seconds. This parameter must be the same for all routers attached to a network. Value values range from 1 to 65,535. The default is 10 seconds. 8. Enter the OSPF Dead Interval for the specified interface in seconds. This specifies how long a router will wait to see a neighbor router's Hello packets before declaring that the router is down. This parameter must be the same for all routers attached to a network. This value should be a multiple of the Hello Interval (for example, 4). Valid values range from 1 to 65,535. The default is 40 seconds. 9. In the Iftransit Delay Interval field, enter the OSPF Transit Delay for the specified interface. This specifies the estimated number of seconds it takes to transmit a link state update packet over the selected interface. Valid values range from 1 to 3600 seconds (1 hour). The default value is 1 second. 10. Configure MTU Ignore by selecting Enable or Disable from the list. MTU Ignore disables OSPF MTU mismatch detection on received database description packets. The default value is Disable (MTU mismatch detection is enabled). 11. Configure Passive Mode by selecting Enable or Disable from the list. Make an interface passive to prevent OSPF from forming an adjacency on an interface. OSPF advertises networks attached to passive interfaces as stub networks. Interfaces are not passive by default, meaning that the Passive Mode default is Disable. 12. Set the OSPF Network Type on the interface by selecting either Broadcast or Point-to-Point from the list. OSPF only selects a designated router and originates network LSAs for broadcast networks. No more than two OSPF routers can be present on a point-to-point link. The default network type for Ethernet interfaces is Broadcast. 13. Select an Authentication Type other than None by selecting from the list. The choices are: • None-This is the initial interface state. If you select this option from the list, no authentication protocols will be run. The default is None. • Simple-If you select Simple, you will be prompted to enter an authentication key. This key will be included, in the clear, in the OSPF header of all packets sent on the network. All routers on the network must be configured with the same key. • Encrypt-If you select Encrypt, you will be prompted to enter an authentication key and an authentication ID. Encryption uses the MD5 Message-Digest algorithm. All routers on the network must be configured with the same key and ID. 14. Enter the Authentication Key ID to be used for authentication. You will only be prompted to enter an ID when you select Encrypt as the authentication type. The ID is a number between 0 and 255, inclusive. 15. In the Metric Cost field, enter the link cost. OSPF uses this value in computing shortest paths. The range is from 1 to 65,535. The default is 1. Routing 274
