Modify interface defaults
OSPF has interface parameters that you can congure. For simplicity, each of these parameters has a default value. No change to these
default values is required except as needed for specic network congurations.
Port default values can be modied using the following CLI commands at the interface conguration level of the CLI:
• ip ospf area
• ip ospf auth-change-wait-time
• ip ospf authentication-key
• ip ospf cost
• ip ospf database-lter all out
• ip ospf dead-interval
• ip ospf hello-interval
• ip ospf md5-authentication key-activation-wait-time
• ip ospf mtu-ignore
• ip ospf passive
• ip ospf active
• ip ospf priority
• ip ospf retransmit-interval
• ip ospf transmit-delay
OSPF interface parameters
The following parameters apply to OSPF interfaces:
• area—Assigns an interface to a
specic area. You can assign either an IP address or number to represent an OSPF Area ID. If
you assign a number, it can be any value from 0 - 2,147,483,647.
• auth-change-wait-time—OSPF gracefully implements authentication changes to allow all routers to implement the change and
thus prevent disruption to neighbor adjacencies. During the authentication-change interval, both the old and new authentication
information is supported. The 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-e10000-1/1/8)# ip ospf authentication-key 0 morningadmin
The software adds a
prex to the authentication key string in the conguration. For example, the following portion of the code
has the encrypted code "2".
ip ospf authentication-key 2 $on-o
The prex 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 dierentiate between
100 Mbps, 1 Gbps, and 10 Gbps. The default cost is calculated by dividing 100 million by the bandwidth. For 10 Mbps links,
