The simple encryption and base 64 encryption methods requires you to configure an alphanumeric password on an
interface. The password can be up to eight characters long. All OSPF packets transmitted on the interface contain this
password. All OSPF packets received on the interface are checked for this password. If the password is not present, then the
packet is dropped.

By default, the authentication key is encrypted. If you want the authentication key to be in clear text, insert a

between

key

and

string

. For example,

device C(config-ospf-router)# area 1 virtual-link 10.0.0.1 authentication-key 0

afternoon

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".

area 1 virtual-link 12.12.12.25 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

md5-authentication key

string

The MD5

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.

When MD5 is enabled, the key-string is an alphanumeric password of up to 16 characters that is later encrypted and
included in each OSPF packet transmitted. You must enter a password in this field when the system is configured to operate
with either simple or MD5 authentication.

By default, the MD5 authentication key is encrypted. If you want the authentication key to be in clear text, insert a

between

key

and

string

. For example,

device(config-ospf-router)# area 1 virtual-link 10.0.0.1 md-5-authentication key-id 5

key evening

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".

device(config-ospf-router)# area 1 virtual-link 12.12.12.25 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

md5-authentication wait
time

This parameter determines when a newly configured MD5 authentication key is valid. This parameter provides a graceful
transition from one MD5 key to another without disturbing the network. All new packets transmitted after the key activation
wait time interval use the newly configured MD5 Key. OSPF packets that contain the old MD5 key are accepted for up to
five minutes after the new MD5 key is in operation.

The range for the key activation wait time is from 0 - 14400 seconds. The default value is 300 seconds.

Changing the reference bandwidth for the cost on OSPF interfaces

Each interface on which OSPF is enabled has a cost associated with it. The device advertises its interfaces and their costs to OSPF
neighbors. For example, if an interface has an OSPF cost of ten, the device advertises the interface with a cost of ten to other OSPF
routers.

By default, an interface’s OSPF cost is based on the port speed of the interface. The cost is calculated by dividing the reference
bandwidth by the port speed. The default reference bandwidth is 100 Mbps, which results in the following default costs:
