default authentication-change interval is 300 seconds (5 minutes). You change the interval to a value
from 0 - 14400 seconds.
• authentication-key string—
By default, the authentication key is encrypted. If you want the authentication key to be in clear text,
insert a 0 between authentication-key and string. For example:
device(config-if-e10000-1/8)# ip ospf authentication-key 0 morningadmin
The software adds a prefix to the authentication key string in the configuration. For example, the
following portion of the code has the encrypted code "2".
ip ospf authentication-key 2 $on-o
The prefix can be one of the following:
‐ 0 = the key string is not encrypted and is in clear text.
‐ 1 = the key string uses proprietary simple cryptographic 2-way algorithm.
• cost—Indicates the overhead required to send a packet across an interface. You can modify the cost
to differentiate between 100 Mbps, 1Gbps, and 10 Gbps. The default cost is calculated by dividing
100 million by the bandwidth. For 10 Mbps links, the cost is 10. The cost for 100 Mbps, 1Gbps, and
10 Gbps links is 1, because the speed of 100 Mbps and 10Gbps was not in use at the time the OSPF
cost formula was devised.
• database-filter—Blocks all outbound LSAs on the OSPF interface.
• dead-interval— Indicates the number of seconds that a neighbor router waits for a hello packet from
the current router before declaring the router down. The value can be from 1 - 65535 seconds. The
default is 40 seconds.
• hello-interval—Represents the length of time between the transmission of hello packets. The value
can be from 1 - 65535 seconds. The default is 10 seconds.
• MD5-authentication activation wait time—The number of seconds the device waits until placing a
new MD5 key into effect. The wait time provides a way to gracefully transition from one MD5 key to
another without disturbing the network. The wait time can be from 0 - 14400 seconds. The default is
300 seconds (5 minutes).
• MD5-authentication key string—The MD5 authentication-key is a number from 1 - 255 and identifies
the MD5 key that is being used. This parameter is required to differentiate among multiple keys
defined on a router.
By default, the authentication key is encrypted. If you want the authentication key to be in clear text,
insert a 0 between authentication-key and string. For example,
device(config-if-e10000-1/8)# ip ospf 1 md-5-authentication key-id 5 key 2
morningadmin
The software adds a prefix to the authentication key string in the configuration. For example, the
following portion of the code has the encrypted code "2".
ip ospf 1 md-5-authentication key-id 5 key 2 $on-o
The prefix can be one of the following:
‐ 0 = the key string is not encrypted and is in clear text.
‐ 1 = the key string uses proprietary simple cryptographic 2-way algorithm.
• mtu-ignore—A database description packet is rejected if the interface MTU specified in the DBD
packet is greater than the MTU of the interface shared between the neighbors. To disable the
mismatch condition set "mtu-ignore". By default, the mismatch detection is enabled.
• passive—When you configure an OSPF interface to be passive, that interface does not send or
receive OSPF route updates. By default, all OSPF interfaces are active and thus can send and
receive OSPF route information. Since a passive interface does not send or receive route
information, the interface is in effect a stub network. OSPF interfaces are active by default.
