Configuring OSPF
Hello Interval: The length of time between the transmission of hello packets. The range is 1
through 65535 seconds. The default is 10 seconds.
Retransmit Interval: The interval between the re-transmission of link state advertisements to
router adjacencies for this interface. The range is 0 through 3600 seconds. The default is 5
seconds.
Transmit Delay: The period of time it takes to transmit Link State Update packets on the interface.
The range is 0 through 3600 seconds. The default is 1 second.
Dead Interval: The number of seconds that a neighbor router waits for a hello packet from the
current router before declaring the router down. The range is 1 through 65535 seconds. The
default is 40 seconds.
Encrypted display of the authentication string or MD5 authentication key
The optional 0 | 1 parameter with the authentication-key and md5-authentication key-id
parameters affects encryption.
For added security, FastIron devices encrypt display of the password or authentication string.
Encryption is enabled by default. The software also provides an optional parameter to disable
encryption of a password or authentication string, on an individual OSPF area or OSPF interface
basis.
When encryption of the passwords or authentication strings is enabled, they are encrypted in the
CLI regardless of the access level you are using.
The encryption option can be omitted (the default) or can be one of the following:
• 0 – Disables encryption for the password or authentication string you specify with the
command. The password or string is shown as clear text in the running-config and the
startup-config file. Use this option of you do not want display of the password or string to be
encrypted.
• 1 – Assumes that the password or authentication string you enter is the encrypted form, and
decrypts the value before using it.
NOTE
If you want the software to assume that the value you enter is the clear-text form, and to encrypt
display of that form, do not enter 0 or 1. Instead, omit the encryption option and allow the software
to use the default behavior.
If you specify encryption option 1, the software assumes that you are entering the encrypted form
of the password or authentication string. In this case, the software decrypts the password or string
you enter before using the value for authentication. If you accidentally enter option 1 followed by
the clear-text version of the password or string, authentication will fail because the value used by
the software will not match the value you intended to use.
Changing the reference bandwidth for the cost
on OSPF interfaces
Each interface on which OSPF is enabled has a cost associated with it. The Layer 3 Switch
advertises its interfaces and their costs to OSPF neighbors. For example, if an interface has an
OSPF cost of ten, the Layer 3 Switch advertises the interface with a cost of ten to other OSPF
routers.
