The following fields can be set:
ParameterDescription
Interface Name | Allows the entry of the name of an IP interface previously |
| configured on the switch. |
Area ID | Allows the entry of an OSPF Area ID configured above. |
Router Priority | Allows the entry of a number between 1 and 255 |
| representing the OSPF priority of the selected area. If a |
| Router Priority of 0 is selected, the switch cannot be elected |
| as the Designated Router for the network. |
Hello Interval | Allows the specification of the interval between the |
| transmission of OSPF Hello packets, in seconds. Between |
| 5 and 65535 seconds can be specified. The Hello Interval, |
| Dead Interval, Authorization Type, and Authorization Key |
| should be the same for all routers on the same network. |
Dead Interval | Allows the specification of the length of time between the |
| receipt of Hello packets from a neighbor router before the |
| selected area declares that router down. An interval |
| between 5 and 65535 seconds can be specified. The Dead |
| Interval must be evenly divisible by the Hello Interval. |
State | Allows the OSPF interface to be disabled for the selected |
| area without changing the configuration for that area. |
Auth Type | This field can be toggled between None, Simple, and MD5 |
| using the space bar. This allows a choice of authorization |
| schemes for OSPF packets that may be exchanged over the |
| OSPF routing domain. None specifies no authorization. |
| Simple uses a simple password to determine if the packets |
| are from an authorized OSPF router. When Simple is |
| selected, the Auth Key field allows the entry of a 8 |
| character password that must be the same as a password |
| configured on a neighbor OSPF router. MD5 uses a |
| cryptographic key entered in the MD5 Key Table |
| Configuration menu. When MD5 is selected, the Auth Key |
| ID field allows the specification of the Key ID as defined in |
| the MD5 configuration above. This must be the same MD5 |
| Key as used by the neighboring router. |
Metric | This field allows the entry of a number between 1 and |
| 65,535 that is representative of the OSPF cost of reaching |
| the selected OSPF interface. The default metric is 1. |

Virtual Interface Configuration
Virtual Interfaces are used by OSPF to link areas that do not have a physical connection to the backbone (also called Area 0) or to link areas of the backbone itself that are discontinuous. This allows routing information to flow from an area that is physically disconnected from area 0 into area 0 by configuring an interface across one of the areas previously defined above.
