OSPF interface settings are described below.
Some OSPF interface settings require previously configured OSPF settings. Read the descriptions
below for details.
Interface NameDisplays the 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 0 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 autho-
rized OSPF router. When Simple is selected, the Auth Key field allows the entry
of an 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 Setting window. 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 representa-
tive of the OSPF cost of reaching the selected OSPF interface. The default
metric is 1.
