• Change the cost associated with OSPF traffic on the interface.
CONFIG-INTERFACE mode
ip ospf cost
– cost: The range is from 1 to 65535 (the default depends on the interface speed).
• Change the time interval the router waits before declaring a neighbor dead.
CONFIG-INTERFACE mode
ip ospf dead-interval seconds
– seconds: the range is from 1 to 65535 (the default is 40 seconds).
The dead interval must be four times the hello interval.
The dead interval must be the same on all routers in the OSPF network.
• Change the time interval between hello-packet transmission.
CONFIG-INTERFACE mode
ip ospf hello-interval seconds
– seconds: the range is from 1 to 65535 (the default is 10 seconds).
The hello interval must be the same on all routers in the OSPF network.
• Use the MD5 algorithm to produce a message digest or key, which is sent instead of the key.
CONFIG-INTERFACE mode
ip ospf message-digest-key keyid md5 key
– keyid: the range is from 1 to 255.
– Key: a character string.
NOTE: Be sure to write down or otherwise record the key. You cannot learn the key after it is
configured. You must be careful when changing this key.
NOTE: You can configure a maximum of six digest keys on an interface. Of the available six
digest keys, the switches select the MD5 key that is common. The remaining MD5 keys are
unused.
• Change the priority of the interface, which is used to determine the Designated Router for the OSPF
broadcast network.
CONFIG-INTERFACE mode
ip ospf priority number
– number: the range is from 0 to 255 (the default is 1).
• Change the retransmission interval between LSAs.
CONFIG-INTERFACE mode
ip ospf retransmit-interval seconds
– seconds: the range is from 1 to 65535 (the default is 5 seconds).
The retransmit interval must be the same on all routers in the OSPF network.
