534
Retransmit Interval - 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.
Hello Interval - 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.
Dead Interval - 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.
Iftransit Delay Interval - 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.
MTU Ignore - Disables OSPF MTU mismatch detection on receiving packets. Default value is Disable.
Authentication Type - You may select an authentication type other than none by clicking on the
'Configure' button. You will then see a new screen, where you can select the authentication type from
the pulldown menu. The choices are:
ƒ None - This is the initial interface state. If you select this option from the pulldown menu on the
second screen you will be returned to the first screen and no authentication protocols will be run.
ƒ 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.
ƒ Encrypt - If you select 'Encrypt' you will be prompted to enter both 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.
Authentication Key - Enter the OSPF Authentication Key for the specified interface. If you do not
choose to use authentication you will not be prompted to enter a key. If you choose 'simple'
authentication you cannot use a key of more than 8 octets. If you choose 'encrypt' the key may be up to
16 octets long. The key value will only be displayed if you are logged on with Read/Write privileges,
otherwise it will be displayed as asterisks.
Authentication ID - Enter the 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 ad 255, inclusive.
Metric Cost - Enter the value on this interface for the cost TOS (type of service). The range for the
metric cost is between 1 and 65,535. Metric Cost is only configurable/displayed if OSPF is initialized on
the interface.
Non-Configurable Data
IP Address - The IP address of the interface.
Subnet Mask - The subnet/network mask, that indicates the portion of the IP interface address that
identifies the attached network.
