Example 1
The following example establishes a virtual link with default values for all optional parameters:
device-name
(config)#
router ospf
device-name
(config-router)#
network 36.0.0.0/8 area 36.0.0.0
device-name
(config-router)#
area 36.0.0.0 virtual-link 36.3.4.5
Example 2
The following example establishes a virtual link with MD5 authentication:
device-name
(config)#
router ospf
device-name
(config-router)#
network 36.0.0.0/8 area 36.0.0.0
device-name
(config-router)#
area 36.0.0.0 virtual-link 36.3.4.5 message-

Configuring OSPF IP Interface Parameters
Certain IP interface-specific OSPF parameters can be altered, as needed. The user does not
required to alter any of these parameters, but some IP interface parameters must be consistent
across all routers in an attached network. Therefore, if the user configures any of these parameters,
be sure that the configurations for all routers on the network have compatible values.
Table 7
lists the commands used to modify the OSPF IP interface parameters.
