ProSafe® Gigabit L3 Managed Stackable Switches Software Administration Manual Admin Mode is enabled: State, Designated Router, Backup Designated Router, Number of Link Events, LSA ACK Interval, and Metric Cost. For OSPF to be fully functional, you must enter a valid IP Address and Subnet Mask via the Interface IP Configuration page or through the CLI command ip address . Note: *Once OSPF is initialized on the router, it will remain initialized until the router is reset. 4. Use Router Priority to enter the OSPF priority for the selected interface. The priority of an interface is specified as an integer from 0 to 255. 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. 5. Use Retransmit Interval to enter 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. 6. Use Hello Interval to enter the OSPF hello interval for the specified interface in seconds. This parameter must be the same for all routers attached to a network. Valid values range from 1 to 65,535. The default is 10 seconds. 7. Use Dead Interval to 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 a multiple of the Hello Interval, e.g., 4. Valid values range from 1 to 2147483647. The default is 40. 8. Use Iftransit Delay Interval to 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. 9. Use MTU Ignore to disable OSPF MTU mismatch detection on received database description packets. Default value is Disable (MTU mismatch detection is enabled). 10. Use Passive Mode to 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. 11. Use Network Type to set the OSPF network type on the interface to broadcast or point-to-point. OSPF only selects a designated router and originates network LSAs for broadcast networks. No more than two OSPF routers may be present on a point-to-point link. The default network type for Ethernet interfaces is broadcast. 280 | Chapter 4. Routing
